Which bulges are favoured by barred S0 galaxies?
Sudhanshu Barway, Kanak Saha, Kaustubh Vaghmare +1
S0 galaxies are known to host classical bulges with a broad range of size and mass, while some such S0s are barred and some not. The origin of the bars has remained as a long-stand…
Broadband X-ray emission and the reality of the broad iron line from the Neutron Star - White Dwarf X-ray binary 4U 1820-30
Aditya S. Mondal, Gulab C. Dewangan, Mayukh Pahari +3
Broad relativistic iron lines from neutron star X-ray binaries are important probes of the inner accretion disk. The X-ray reflection features can be weakened due to strong magneti…
UV and X-Ray Variability of the Narrow-Line Seyfert 1 Galaxy Ark 564
Savithri H. Ezhikode, Gulab C. Dewangan, Ranjeev Misra +3
We analyse eight XMM-Newton observations of the bright Narrow-Line Seyfert 1 galaxy Arakelian 564 (Ark 564). These observations, separated by ~6 days, allow us to look for correlat…
Warm Absorbers in X-rays (WAX), a comprehensive high resolution grating spectral study of a sample of Seyfert Galaxies: II. Warm Absorber dynamics and feedback to galaxies
Sibasish Laha, Matteo Guainazzi, Susmita Chakravorty +2
This paper is a sequel to the extensive study of warm absorber (WA) in X-rays carried out using high resolution grating spectral data from XMM-Newton satellite (WAX-I). Here we dis…
