Deciphering of physical characteristics of a rare class of supernovae hint towards advanced stage of evolution of special class of very hot, massive stars

New Delhi, August 17, 2022: A team of scientists have deciphered the physical characteristics of a rare class of supernovae called Type Ibn Supernovae (SNe). Type Ibn supernovae are a rare class of stripped-envelope supernovae interacting with a helium-rich dense circumstellar medium (CSM). These SNe are unique and essential because they help to explore about the typical density, […]

Scientists trace first clue to understand transient high energy pulses from magnetars several thousand times to that of the Sun

New Delhi, December 26, 2021: Scientists have found the first clues to understand violent short duration flares from a compact star of rare category called magnetars located thirteen million light years away. These compact stars with the most intense magnetic field known, of which only thirty have been spotted so far in our galaxy, suffer […]

Resolution of scientific challenge in calculating chemical abundance in stars can help explore their history better

New Delhi, September 23, 2021: The probe of astronomers into the history of formation and evolution of stars through chemical constitution of the bodies has long been hampered by an intriguing ‘carbon problem’—a mismatch between predicted and observed values of an abundance of elements that prevented the scientists from correctly calculating the abundances of the […]

Researchers Discover Three Super-massive Black Holes Merging Together in Our Nearby Universe

New Delhi, August 28, 2021: Indian researchers have discovered three supermassive black holes from three galaxies merging together to form a triple active galactic nucleus, a compact region at the center of a newly discovered galaxy that has a much-higher-than-normal luminosity. This rare occurrence in our nearby Universe indicates that small merging groups are ideal […]
