• Constraints on the epoch of dark matter formation from Milky Way satellites 

  Das, Subinoy; Nadler, E. O (The American Physical Society, 2021-02-15)

  A small fraction of thermalized dark radiation that transitions into cold dark matter (CDM) between big bang nucleosynthesis and matter-radiation equality can account for the entire dark matter relic density. Because of ...
• Discovery of an M-type companion to the Herbig Ae Star V1787 Ori 

  Arun, R; Mathew, B; Rengaswamy, S; Manoj, P; Narang, M; Kartha, S. S; Maheshwar, G (Oxford University Press on behalf of the Royal Astronomical Society, 2021-02)

  The intermediate-mass Herbig Ae star V1787 Ori is a member of the L1641 star-forming region in the Orion A molecular cloud. We report the detection of an M-type companion to V1787 Ori at a projected separation of 6.66 arcsec ...
• The First Extensive Exploration of UV-bright Stars in the Globular Cluster NGC 2808 

  Prabhu, D. S; Subramaniam, A; Snehalata Sahu (IOP Publishing, 2021-02-10)

  In this study, we identified and characterized the hot and luminous UV-bright stars in the globular cluster NGC 2808. We combined data from the Ultra Violet Imaging Telescope (UVIT) on board the Indian space satellite AstroSat ...
• Long-term (2008–2018) aerosol properties and radiative effect at high-altitude sites over western trans-Himalayas 

  Dumka, U. C; Shantikumar, N. S; Kaskaoutis, D. G; Madhavan, B. L; Song, H. -J; Angchuk, D; Jorphail, S (Elsevier B. V, 2020-09-10)

  Analysis of the climatology of aerosol properties is performed over Hanle (4500 m) and Merak (4310 m), two remote-background sites in the western trans-Himalayas, based on eleven years (2008–2018) of sun/sky radiometer ...
• Optical and physical properties of aerosols during active fire events occurring in the Indo-Gangetic Plains: Implications for aerosol radiative forcing 

  Shantikumar, N. S; Dumka, U. C; Srivastava, A. K; Song, H. -J (Elsevier B. V, 2020-02-15)

  The climatological characteristics of biomass burning over the western Indo-Gangetic Plain (IGP) are examined during the post-monsoon (October-November) season from 2001-2018 using the Moderate resolution Imaging Spectrometer ...
