Highly reddened type Ia supernova SN 2004ab: another case of anomalous extinction
N. K. Chakradhari, D. K. Sahu, G. C. Anupama +1
We present optical photometric and spectroscopic results of supernova SN 2004ab, a highly reddened normal type Ia supernova. The total reddening is estimated as = 1.70 $\p…
Long-term study of Mkn 421 with the HAGAR Array of Telescopes
Atreyee Sinha, Amit Shukla, Lab Saha +8
Context:The HAGAR Telescope Array at Hanle, Ladakh has been regularly monitoring the nearby blazar Mkn 421 for the past 7yrs. Aims: Blazars show flux variability in all timescales…
Investigating AGN Black Hole Masses and the M- relation for Low Surface Brightness Galaxies
Smitha Subramanian, Ramya. S, Mousumi Das +3
We present an analysis of the optical nuclear spectra from the active galactic nuclei (AGN) in a sample of low surface brightness (LSB) galaxies. Using data from the Sloan Digital…
Modelling the synchrotron light curves in recurrent novae V745 Scorpii and RS Ophiuchi
N. G. Kantharia, P. Dutta, N. Roy +6
In this paper, we present the synchrotron light curve at 610 MHz from the recurrent nova V745 Sco following its outburst on 6 February 2014. The system has been detected and period…
Investigating the AGN activity and black hole masses in Low Surface brightness galaxies
Smitha Subramanian., Ramya. S., Mousumi Das. +3
We present an analysis of the optical nuclear spectra from the active galactic nuclei (AGN) in a sample of giant low surface brightness (GLSB) galaxies. GLSB galaxies are extreme l…
Strong Lens Time Delay Challenge: II. Results of TDC1
Kai Liao, Tommaso Treu, Phil Marshall +23
We present the results of the first strong lens time delay challenge. The motivation, experimental design, and entry level challenge are described in a companion paper. This paper…
