Fermi monitoring of radio-loud narrow-line seyfert 1 galaxies

Paliya, Vaidehi S; Stalin, C. S; Ravikumar, C. D (IOP Publishing, 2015-02)

We present detailed analysis of the γ-ray flux variability and spectral properties of the five radio-loud narrow line Seyfert 1 (RL-NLSy1) galaxies, detected by the Large Area Telescope on board the Fermi Gamma-Ray Space ...
Interacting system NGC 7805/6 (Arp 112) and its tidal dwarf galaxy candidate

Fu, Zhen-Xing; Sengupta, Chandreyee; Ramya, S; Pradhan, Bikram; Singh, Mridweeka; Misra, K; Scott, Tom. C; Ma, Yin-Zhe (IOP Publishing, 2021-02)

We present results from our Giant Metrewave Radio Telescope (GMRT) Hi, Himalayan Chandra Telescope (HCT) Hα, 1 m Sampurnanand Telescope (ST) and 1.3 m Devasthal Fast Optical Telescope (DFOT) deep optical observations of ...
Remnants of recent mergers in nearby early-type galaxies and their classification

Giri, Gourab; Barway, Sudhanshu; Raychaudhury, Somak (Oxford University Press on behalf of Royal Astronomical Society, 2023-04)

We search for signatures of recent galaxy close interactions and mergers in a sample of 202 early-type galaxies in the local universe from the public SDSS Stripe82 deep images (μr ∼ 28.5 mag arcsec−2). Using two different ...
