A Partial Near-infrared Guide Star Catalog for Thirty Meter Telescope Operations

Shah, Sarang; Subramanian, S; Avinash, Ck; Andersen, David R; Skidmore, Warren; Anupama, G. C; Delgado, Francisco; Gillies, Kim; Maheshwar, G; Ramaprakash, A. N; Reddy, B. E; Sivarani, T; Subramaniam, A (American Astronomical Society, 2024-08-01)

At first light, the Thirty Meter Telescope (TMT) near-infrared (NIR) instruments will be fed by a multiconjugate adaptive optics instrument known as the Narrow Field Infrared Adaptive Optics System (NFIRAOS). NFIRAOS will ...
SN 2020jfo: A Short-plateau Type II Supernova from a Low-mass Progenitor

Teja, Rishabh Singh; Singh, A; Sahu, D. K; Anupama, G. C; Kumar, Brajesh; Nayana, A. J (American Astronomical Society, 2022-05-01)

We present spectroscopic and photometric observations of the Type IIP supernova, SN 2020jfo, in ultraviolet and optical wavelengths. SN 2020jfo occurred in the spiral galaxy M61 (NGC 4303), with eight observed supernovae ...
SN 2021wvw: a core-collapse supernova at the subluminous, slower, and shorter end of type IIPs

Teja, Rishabh Singh; Goldberg, Jared A; Sahu, D. K; Anupama, G. C; Singh, Avinash; Swain, Vishwajeet; Bhalerao, Varun (American Astronomical Society., 2024-10-10)

We present detailed multiband photometric and spectroscopic observations and analysis of a rare core-collapse supernova, SN 2021wvw, that includes photometric evolution up to 250 days and spectroscopic coverage up to 100 ...
