Study of short term enhanced TeV - ray emission from Mrk 421 observed with TACTIC on December 28, 2014
K K Singh, K K Yadav, K Chanchalani +19
In this work, we report on the detection of enhanced TeV gamma- ray emission from the high synchrotron-peaked blazar Mrk 421 with the TACTIC telescope on the night of December 28,…
An Automated tool to detect variable sources in the Vista Variables in the V\'ıa Láctea Survey. The VVV Variables (V) catalog of tiles d001 and d002
Nicolás Medina, Jura Borissova, Amelia Bayo +8
Time-varying phenomena are one of the most substantial sources of astrophysical information and their study has led to many fundamental discoveries in modern astronomy. We have dev…
Multiwavelength study of VHE emission from Markarian 501 using TACTIC observations during April-May, 2012
P Chandra, K K Singh, R C Rannot +23
We have observed Markarian 501 in Very High Energy (VHE) gamma-ray wavelength band for 70.6 hours from 15 April to 30 May, 2012 using TACTIC telescope. Detailed analysis of 6…
A time dependent approach to model X-ray and --ray light curves of Mrk 421 observed during the flare in February 2010
K K Singh, S Sahayanathan, A Sinha +18
Strong X-ray and --ray flares have been detected in February 2010 from the high synchrotron peaked blazar Mrk 421 (z=0.031). With the motivation of understanding the physics inv…
Infrared spectroscopy of eruptive variable protostars from VVV
C. Contreras Peña, P. W. Lucas, R. Kurtev +11
In a companion work (Paper I) we detected a large population of highly variable Young Stellar Objects (YSOs) in the Vista Variables in the Via Lactea (VVV) survey, typically with c…
Search for TeV --ray emission from blazar 1ES1218+304 with TACTIC telescope during March-April 2013
K. K. Singh, K. K. Yadav, A. K. Tickoo +22
In this paper, we present results of TeV --ray observations of the high synchrotron peaked BL Lac object 1ES 1218+304 (z=0.182) with the (TeV Atmospheric Cherenkov Tele…
