Astronomers discover 83 supermassive black holes 13 billion light-years away

Washington, Mar 15: Astronomers have discovered 83 quasars powered by supermassive black holes 13 billion light-years away from the Earth, from a time when the universe was less than 10 per cent of its present age.

“It is remarkable that such massive dense objects were able to form so soon after the Big Bang,” said Michael Strauss, a professor at Princeton University in the US.

“Understanding how black holes can form in the early universe, and just how common they are, is a challenge for our cosmological models,” Strauss said in a statement.

This finding, published in The Astrophysical Journal, increases the number of black holes known at that epoch  considerably, and reveals, for the first time, how common they are early in the universe’s history.

In addition, it provides new insight into the effect of black holes on the physical state of gas in the early universe in its first billion years.

Supermassive black holes, found at the centers of galaxies, can be millions or even billions of times more massive than the Sun.

While they are prevalent today, it is unclear when they first formed, and how many existed in the distant early universe.

A supermassive black hole becomes visible when gas accretes onto it, causing it to shine as a “quasar.” Previous studies have been sensitive only to the very rare, most luminous quasars, and thus the most massive black holes.

The new discoveries probe the population of fainter quasars, powered by black holes with masses comparable to most black holes seen in the present-day universe.

The team used data taken with “Hyper Suprime-Cam” (HSC) instrument, mounted on the Subaru Telescope of the National Astronomical Observatory of Japan, which is located on the summit of Maunakea in Hawaii.

The researchers selected distant quasar candidates from the sensitive HSC survey data.

They then carried out an intensive observational campaign to obtain spectra of those candidates, using three telescopes: the Subaru Telescope; the Gran Telescopio Canarias on the island of La Palma in the Canaries, Spain; and the Gemini South Telescope in Chile.

The survey revealed 83 previously unknown very distant quasars.

Bengaluru: As the dust settles on the recent legislative session, the corridors of Vidhana Soudha are buzzing with more than just policy talk. A high-stakes game of political musical chairs has begun, exposing a deepening rift within the Congress party’s Muslim leadership as a major Cabinet reshuffle looms.

With the party hierarchy signaling a "50% refresh" to gear up for the 2028 Assembly elections, the race to fill three projected Muslim ministerial berths has transformed from a strategic discussion into an all-out turf war.

The "Star Son" Spark

The internal friction turned public this week following provocative remarks by Zaid Khan, actor and son of Wakf Minister Zameer Ahmed Khan. Zaid’s claim—that his father "helped" secure a ticket for Shivajinagar MLA Rizwan Arshad in 2023—has acted as a lightning rod for resentment.

Rizwan’s camp was quick to fire back, dismissing the comment as a desperate attempt by Zameer to manufacture seniority. "Rizwan’s political pedigree was forged in the NSUI and Youth Congress long before Zameer even stepped into the party," a supporter noted, highlighting Rizwan’s tenure as an AICC secretary and his two-term presidency of the State Youth Congress.

A Tale of Two Loyalists

While both Zameer Ahmed Khan and Rizwan Arshad are staunch allies of Chief Minister Siddaramaiah and represent Bengaluru strongholds, their political DNA could not be more different:

•    Zameer Ahmed Khan: A four-time MLA who crossed over from JD(S) in 2018. Known for his "overzealous" and often polarizing outreach during communal flashpoints—from the DJ Halli riots to the recent Wakf land notice controversy—his style has frequently left the Congress high command in a state of "discomfort."

•    Rizwan Arshad: A homegrown organizational man. Seen as a "quiet performer," Arshad represents the sophisticated, moderate face of the party, preferred by those who find Zameer’s brand of politics too volatile.

The Outsiders Looking In

The bickering isn't limited to a duo. The "Beary" community, represented by leaders like N A Haris and Saleem Ahmed, is demanding its pound of flesh. Saleem Ahmed, the Chief Whip in the Legislative Council, has dropped the veil of diplomacy, openly declaring his ministerial aspirations.

"I was the only working president not included in the Cabinet last time," Saleem noted pointedly, signaling that the "loyalty quota" is no longer enough to keep the peace.

As Chief Minister Siddaramaiah prepares to finalize the list, he faces a delicate balancing act: rewarding the aggressive grassroots mobilization of Zameer’s camp without alienating the organizational stalwarts and minority sub-sects who feel increasingly sidelined by the "Chamarajpet-Shivajinagar" binary.

New Delhi: Setting speculation to the rest, the CPI(M) has made it clear that it is open to have an electoral understanding with the Congress “to defeat” the Trinamool Congress and the BJP in West Bengal Assembly election even as it is all set to take on the grand old party in Kerala accusing it of “found wanting” in fighting the Hindutva forces.

The CPI(M) also said that it will contest the Tamil Nadu election “with DMK and its allies to defeat the BJP and its allies”, amid a section in the Congress triggering confusion about its participation in the M K Stalin-led coalition over demand over power-sharing and more seats. It is also willing to join hands with Congress and others in Assam and Puducherry to defeat the BJP.

The decisions came at a three-day meeting of the CPI(M) Central Committee in Thiruvananthapuram, which ended on Sunday after reviewing the poll preparations in the poll-bound states.

The CPI(M)'s decision came even as a section led by West Bengal Congress president Subhankar Sarkar is averse to tying up with the Left Front, claiming that their party is not benefitted by the electoral understanding. Both Congress and CPI(M)-led Left Front had electoral understanding in 2016 and 2021 Assembly elections and 2024 Lok Sabha polls.

Congress and the Left Front fought together for the first time in 2016 when Congress won 44 seats and the CPI(M) got 26. In 2021, the Left Front and the Congress drew a blank. In the 2024 Lok Sabha polls, Congress managed to win one seat while the Left did not win any. In the 2019 Lok Sabha polls, both fought against each other with Congress winning two and the Left none.

“In Bengal, the party will work for the defeat of both the TMC and the BJP, which are trying to polarise the society. We will try to rally all the forces that are ready to work against them,” the CPI(M) said in a statement without naming Congress by name. Senior leaders said there is no change in its strategy of pooling all non-BJP, non-TMC votes.

However, the party was critical of the Congress in Kerala where both will fight against each other.

The CPI(M) said it would "expose the BJP-led Union government’s denial of rightful dues to Kerala, the fiscal constraints imposed and the overall attack on federalism" as also "expose the failure of the Congress to effectively counter this attack on federalism, as the largest opposition party in the Parliament".

"The Congress, especially in Kerala, was found wanting in the fight against communal RSS-BJP, ideologically and this will also be exposed before the people," it added.

In Assam, it said, the CPI(M) will work for the mobilisation of all the anti-BJP parties and forces and defeat the rabidly communal and divisive BJP government. The Left parties are cooperating with Congress in the north-eastern state. In Puducherry, it said it will work for the defeat of the BJP alliance government.

Mangaluru: Mangaluru’s skyline is set for a high-end transformation as the coastal district of Dakshina Kannada prepares to shed its reputation for lacking premium hospitality. In a massive show of confidence, entrepreneurs have committed nearly ₹500 crores toward the construction of four new five-star hotels, a move experts say will finally plug the "luxury leak" to neighboring states.

For years, Mangaluru International Airport (MIA) has served as a gateway for high-net-worth travelers who, upon landing, promptly departed for Kerala or Kodagu due to a dearth of elite accommodation in the city. These new projects, three of which are backed by local visionary investors, aim to turn Mangaluru into a destination rather than just a transit point.

Mapping the Luxury Boom

The expansion is already in motion, with two major landmarks leading the charge:
•    Gurupura Property: Construction is already underway on a premier resort-style hotel.
•    Kuloor Hub: A sophisticated urban luxury hotel has been proposed for this strategic area.
•    Timeline: All four projects are slated for completion within the next 24 months, promising to fundamentally alter the region's tourism profile by 2028.

Why Now? The Investor Demand

The push for five-star infrastructure isn't just about tourism; it’s a direct response to the city’s industrial and academic evolution. Stakeholders from the IT and corporate sectors have long flagged the lack of premium suites as a hurdle for international business investments.

"Mangaluru is an powerhouse of mega-industries, medical excellence, and a burgeoning IT scene," noted a senior Tourism Department official. "It is an anomaly that a city with this much economic muscle has lacked a five-star anchor. By offering premium hospitality, we aren't just housing tourists; we are inviting global investors to stay, engage, and invest more deeply in our coast."

Strategic Retention

The "drain" of visitors to the neighboring state of Kerala has been a long-standing grievance for local businesses. With these new properties, the district administration expects a significant multiplier effect—benefiting local sightseeing, high-end retail, and the burgeoning medical tourism sector. As Mangaluru accelerates on its development trajectory, the message to the world is clear: the coast is finally ready to host you in style.
