Detection of HI 21 cm emission from a strongly lensed galaxy at z~1.3
Arnab Chakraborty, Nirupam Roy
We report the first detection of HI 21 cm emission from a star-forming galaxy at redshift (nearly 9 billion years ago) using upgraded Giant Metrewave Radio Telescop…
LAMOST J045019.27+394758.7, with peculiar abundances of N, Na, V, Zn, is possibly a Sculptor dwarf galaxy escapee
Meenakshi Purandardas, Aruna Goswami, J. Shejeelammal +5
We present the results of the high-resolution (R60,000) spectroscopic analysis of the star LAMOSTJ045019.27+394758.7 (hereafter J045) from the list of carbon stars of LAMOST…
Long term Ultra-Violet Variability of Seyfert galaxies
N. Sukanya, C. S. Stalin, P. Joseph +3
Flux variability is one of the defining characteristics of Seyfert galaxies, a class of active galactic nuclei (AGN). Though these variations are observed over a wide range of wave…
Long-term optical flux and colour variability in quasars
N. Sukanya, C. S. Stalin, S. Jeyakumar +3
We have used optical V and R band observations from the Massive Compact Halo Object (MACHO) project on a sample of 59 quasars behind the Magellanic clouds to study their long term…
