  • AT2020ohl: its nature and probable implications 
    Roy, Rupak; Mandal, Samir; Sahu, D. K; Anupama, G. C; Nandi, Sumana; Kumar, Brijesh (Oxford University Press on behalf of Royal Astronomical Society., 2024-03)
    ASASSN-20hx, a.k.a AT2020ohl, is an ambiguous nuclear transient, which was discovered in the nearby galaxy NGC6297 by the All-Sky Automated Survey for Supernovae. We have investigated the evolution of AT2020ohl using a ...
  • COSMOGLOBE DR1 results. I. Improved Wilkinson Microwave Anisotropy Probe maps through Bayesian end-to-end analysis 
    Watts, D. J; Basyrov, A; Eskilt, J. R; Galloway, M; Gjerlow, E; Hergt, L. T; Herman, D; Ihle, H. T; Paradiso, S; Fazlu, Rahman; Thommesen, H; Aurlien, R; Bersanelli, M; Bianchi, L. A; Brilenkov, M; Colombo, L. P. L; Eriksen, H. K; Franceschet, C; Fuskeland, U; Hensley, B; Hoerning, G. A; Lee, K; Lunde, J. G. S; Marins, A; Nerval, S. K; Patel, S. K; Regnier, M; San, M; Sanyal, S; Stutzer, N.O; Verma, A; Wehus, I. K; Zhou, Y (EDP Sciences, 2023-11)
    We present COSMOGLOBE Data Release 1, which implements the first joint analysis of WMAP and Planck LFI time-ordered data, processed within a single Bayesian end-to-end framework. This framework directly builds on a similar ...
  • Evidence of underdeveloped torus and broad-line region of weak emission line quasars based on their spectral energy distribution 
    Kumar, Ritish; Chand, Hum; Joshi, Ravi (Oxford University Press on behalf of Royal Astronomical Society, 2023-03)
    To unravel the dominant cause of the weak emission line in a subset of optically selected radio-quiet 'weak emission line quasars' (WLQs), we have investigated the possibility of an underdeveloped broad line region (BLR). ...
  • Photometric identification of objects from Galaxy Evolution Explorer Survey and Sloan Digital Sky Survey 
    Preethi, K; Gudennavar, S. B; Bubbly, S. G; Murthy, J; Brosch, N (Oxford University Press on behalf of the Royal Astronomical Society, 2014-01-01)
    We have used Galaxy Evolution Explorer (GALEX) and Sloan Digital Sky Survey (SDSS) observations to extract seven band photometric magnitudes for over 80 000 objects in the vicinity of the North Galactic Pole. Although these ...
  • Properties of radio-loud quasars in the Sloan Digital Sky Survey 
    Gaur, H; Gu, M; Ramya, S; Guo, H (EDP Sciences, 2019-11)
    We present a study of a sample of 223 radio-loud quasars (up to redshift < 0.3) in order to investigate their spectral properties. Twenty-six of these radio-loud quasars are identified as flat-spectrum radio quasars (FSRQs), ...
