Broad-band temporal and spectral study of TeV blazar TXS 0518+211
Avik Kumar Das, Pankaj Kushwaha, Veeresh Singh +3
We present a long-term broad-band temporal and spectral study of a TeV BL Lac source TXS 0518+211 by analyzing nearly 16 years (MJD 54682 -- 60670) of simultaneous optical, UV and…
Explaining the Origin of TeV Gamma Rays from M87 During High and Low States
Nibedita Mondal, Sandeep Kumar Mondal, Nayantara Gupta
The detection of very high-energy gamma-rays from M87 can provide crucial insights into particle acceleration and radiation mechanisms in jets. The recent observations by the Large…
Unraveling the Emission Mechanism of the HBL Source Mrk 180 with Multi-Wavelength Data
Sandeep Kumar Mondal, Saikat Das, Nayantara Gupta
Markarian (Mrk) 180 is a High frequency-peaked BL Lacertae object or HBL object, located at a redshift of 0.045 and a potential candidate for high-energy cosmic ray acceleration. I…
Multi-wavelength temporal and spectral study of PKS 0402-362
Avik kumar Das, Sandeep Kumar Mondal, Raj Prince
We study the long-term behavior of the bright gamma-ray blazar PKS 0402-362. Over a span of approximately 12.5 years, from August 2008 to January 2021, we gathered Fermi-LAT tempor…
Gamma-ray flares and broadband spectral study of PKS 0402-362
Avik Kumar Das, Sandeep Kumar Mondal, Raj prince
We study the long-term behavior of the bright gamma-ray blazar PKS 0402-362. We collected approximately 13 years of Fermi-LAT data between Aug 2008 to Jan 2021 and identified three…
Exploring the Emission Mechanisms of Mrk 180 with long term X-ray and -ray data
Sandeep Kumar Mondal, Saikat Das, Nayantara Gupta
Markarian (Mrk) 180 is a BL Lacertae (BL Lac) object located at a redshift of 0.045 and a potential candidate for high-energy cosmic ray acceleration. We have analyzed the Fermi La…
Spectral Modeling of Flares in Long Term Gamma-Ray Light Curve of PKS 0903-57
Sandeep Kumar Mondal, Raj Prince, Nayantara Gupta +1
A detailed study of the BL Lacertae PKS 0903-57 has been done for the first time with 12 years of Fermi Large Area Telescope data. We have identified two bright gamma-ray flares in…
