"A ‘Now I See You’ Moment" for Andhra-Origins Scientist: How Her Team Identified 2,500 Potential Black Holes
[Bengaluru:] To spot a black hole is tough, and to find them in smaller galaxies is even more difficult. But that didn’t stop Dr. Ragadeepika Pucha, a postdoctoral researcher of Indian origin at the University of Utah, from pushing the boundaries of astrophysical exploration.
The "Now I See You" Moment: Unveiling the Presence of 2,500 Potential Black Holes
Dr. Pucha’s team sifted through early data provided by the Dark Energy Spectroscopic Instrument (DESI), an astronomical instrument in Arizona that measures the effect of dark energy on the expansion of the universe. Their meticulous analysis allowed them to identify 2,500 potentially active black holes in dwarf galaxies, and detect the presence of 300 new intermediate mass black hole candidates. Both findings represent the largest and most extensive collections to date, tripling the existing census of high-energy galactic centers and doubling the number of intermediate black holes.
Unlocking the Secrets of Black Holes and Galaxies
According to a press release by NOIRLab, the US National Centre for Ground-Based, Night-Time Optical and Infrared Astronomy, Dr. Pucha’s discovery marks a significant milestone in understanding the formation and evolution of black holes. "This is the first time we have a statistical sample of candidates which will help us investigate what is happening between galaxies and central black holes, which we did not have until now," she explained.
Dr. Pucha’s Journey: A "Now I See You" Moment for Andhra-Origins Scientist
Born in Tenali, Guntur, Dr. Pucha’s journey is a testament to the power of dedication and research. "I want to understand how dwarf galaxies formed and evolved," she said. After spending the last four years surging through vast data, Dr. Pucha’s achievement is a remarkable example of Indian scientific talent making a global impact.
Unraveling the Enigma of Black Holes and Galaxies
The discovery of intermediate mass black hole candidates has been a long-sought goal for scientists. While supermassive black holes (imagine an adult) have been confirmed, the mechanism of their formation remains a mystery. "The theory further assumed that these intermediate mass black holes would be found in the center of dwarf galaxies rather than massive ones," Dr. Pucha elaborated. "But our findings show that only 70 of these candidates are actually in dwarf galaxies. Most of them are actually in massive galaxies."

In the search for black holes, scientists have traditionally focused on the centers of massive galaxies. However, Dr. Pucha’s team has shown that black holes are actually more common in smaller galaxies. "With the large population discovered by DESI, scientists now have a new dataset to use to study these cosmic enigmas," according to NOIRLab.
In Conclusion:
The "Now I See You" moment for Dr. Pucha and her team marks a significant milestone in astrophysical research. As we continue to unravel the mysteries of black holes and galaxies, we are reminded of the importance of dedication, persistence, and collaboration in scientific inquiry. With their groundbreaking discovery, Dr. Pucha and her team have illuminated a new path for scientists to explore, paving the way for further discoveries and a deeper understanding of our universe.
