Positive AGN feedback in the outskirts of nearby barred spiral galaxies?
Bannanje Ananthamoorthy, Debbijoy Bhattacharya, P. Sreekumar
Observational evidence regarding the impact of AGN feedback on star formation (SF) in non-jetted galaxies is limited. With the available high-resolution UV observations from AstroS…
Detection of Faint Sources by the UltraViolet Imaging Telescope Onboard AstroSat Using Poisson Distribution of Background
B. Ananthamoorthy, Debbijoy Bhattacharya, P. Sreekumar +1
We present an improved approach for constructing the UV source catalogs using observations from the UltraViolet Imaging Telescope (UVIT) onboard AstroSat, by considering the Poisso…
Enhanced UV emission knot in the giant radio galaxy NGC 315: Hint of patchy star formation?
Bannanje Ananthamoorthy, Debbijoy Bhattacharya, Dipanjan Mukherjee +1
High-resolution AstroSat-UltraViolet Imaging Telescope (UVIT) observations revealed a knot of UV emission, kpc away from the centre of NGC 315, a nearby elliptical galax…
Exploring the Origins of Optical Variability in AGNs: Correlations with Black Hole Properties, X-ray, and Radio Emission
Vivek Kumar Jha, Debbijoy Bhattacharya, Hum Chand
We study the optical variability characteristics of Active Galactic Nuclei (AGN) from the Swift Burst Alert Telescope (BAT) AGN catalogue by utilising approximately five years of o…
Multi-epoch UV X-ray spectral study of NGC 4151 with AstroSat
Shrabani Kumar, G. C. Dewangan, P. Gandhi +8
We present a multi-wavelength spectral study of NGC 4151 based on five epochs of simultaneous AstroSat observations in the near ultra-violet (NUV) to hard X-ray band ($\sim 0.005-8…
AstroSat/UVIT Study of the Diffuse Ultraviolet Radiation in the Dwarf Galaxy Holmberg II
Olag Pratim Bordoloi, B. Ananthamoorthy, P. Shalima +4
We present measurements of diffuse ultraviolet emission in the dwarf irregular galaxy Holmberg II obtained with the UltraViolet Imaging Telescope (UVIT) onboard AstroSat. With a sp…
