Spectral energy distributions of the BL Lac PKS 2155-304 from XMM-Newton
Jai Bhagwan, Alok C. Gupta, I. E. Papadakis +1
We have used all 20 archival XMM-Newton observations of PKS 2155-304 with simultaneous X-ray and UV/optical data to study its long term flux and spectral variability. We find signi…
Isophotal shapes of early-type galaxies to very faint levels
Laxmikant Chaware, Russell Cannon, Ajit K. Kembhavi +1
We report on a study of the isophotal shapes of early-type galaxies, to very faint levels reaching ~ 0.1% of the sky brightness. The galaxies are from the Large Format Camera (LFC)…
Supernova SN 2012dn: A spectroscopic clone of SN 2006gz
N. K. Chakradhari, D. K. Sahu, S. Srivastav +1
We present optical and UV analysis of the luminous type Ia supernova SN 2012dn covering the period 11 to +109 days with respect to the band maximum, that occurred on JD…
Apex determination and detection of stellar clumps in the open cluster M 67
S. V. Vereshchagin, N. V. Chupina, Devesh P. Sariya +2
We determined the cluster apex coordinates, studied the substructures and performed membership analysis in the central part (34'X33') of the open cluster M 67. We used the individu…
Study of Dust and Ionized gas in Early-type Galaxies
Samridhi Kulkarni, D. K. Sahu, Laxmikant Chaware +2
We present results of optical broad-band and narrow-band Halpha observations of a sample of forty nearby early-type galaxies. The majority of sample galaxies are known to have dust…
