Discovery of a rich population of compact hub-filament systems in a single star-forming complex
L. K. Dewangan, Ram K. Yadav, Saurabh Sharma +4
We report the discovery of 45 compact hub-filament systems (HFSs; median size 2.4 pc) in infrared-dark clouds (IRDCs) in the W33 complex, located at the junction of the Scutu…
Study of variability in long-term multiwavelength optical lightcurves of blazar AO 0235+164
Abhradeep Roy, Alok C. Gupta, Varsha R. Chitnis +9
We present a long-term and intraday variability study on optical multiwaveband () data from the blazar AO 0235+164 collected by various telescopes for 44 years (19…
Transient Quasi-Periodic Oscillations at -rays in the TeV Blazar PKS 1510-089
Abhradeep Roy, Arkadipta Sarkar, Anshu Chatterjee +3
We present periodicity search analyses on the -ray lightcurve of the TeV blazar PKS 1510-089 observed by the \textit{Fermi} Large Area Telescope. We report the detection of two…
Are there broad absorption-line blazars?
Sapna Mishra, Gopal-Krishna, Hum Chand +2
We report the first systematic search for blazars among broad-absorption-line (BAL) quasars. This is based on our intranight optical monitoring of a well-defined sample of 10 candi…
Photometric and Spectroscopic study of a highly reddened type Ia supernova SN 2003hx in NGC 2076
Kuntal Misra, D. K. Sahu, G. C. Anupama +1
We present CCD photometry and optical spectra of the type Ia supernova SN 2003hx which appeared in the galaxy NGC 2076, obtained till 146 days after the epoch of …
Type IIP Supernova SN 2004et: A Multi-Wavelength Study in X-Ray, Optical and Radio
Kuntal Misra, Dave Pooley, Poonam Chandra +4
We present X-ray, broad band optical and low frequency radio observations of the bright type IIP supernova SN 2004et. The \cxo observed the supernova at three epochs, and the optic…
