  • The Nature of jets in double-peaked emission-line AGN in the KISSR sample 
    Kharb, P; Subramanian, S; Mousumi Das; Vaddi, S; Paragi, Z (IOP Publishing, 2021-10-01)
    Double-peaked emission-line AGN (DPAGN) have been regarded as binary black hole candidates. We present here results from parsec-scale radio observations with the Very Long Baseline Array (VLBA) of five DPAGN belonging to ...
  • Intermediate luminosity type Iax supernova 2019muj with narrow absorption lines: long-lasting radiation associated with a possible bound remnant predicted by the weak deflagration model 
    Kawabata, Miho; Maeda, Keiichi; Yamanaka, Masayuki; Nakaoka, Tatsuya; Kawabata, Koji S; Aoki, Kentaro; Anupama, G. C; Burgaz, Umut; Anirban Dutta; Isogai, Keisuke; Kino, Masaru; Kojiguchi, Naoto; Kota, Iida; Brajesh Kumar; Kuroda, Daisuke; Maehara, Hiroyuki; Matsubayash, Kazuya; Morihana, Kumiko; Murata, Katsuhiro L; Ohshima, Tomohito; Otsuka, Masaaki; Sahu, D. K; Avinash Singh; Sugitani, Koji; Takahashi, Jun; Takagi, Kengo (Oxford University Press on behalf of the Astronomical Society of Japan, 2021-10)
    We present comprehensive spectroscopic and photometric analyses of the intermediate luminosity type Iax supernova (SN Iax) 2019muj based on multi-band datasets observed through the framework of the OISTER target-of-opportunity ...
  • Echo mapping of active galactic nuclei 
    Amit Kumar Mandal (Indian Institute of Astrophysics, 2021-06)
    Active galactic nuclei (AGN) are the persistent high luminosity sources powered by accretion of matter onto super massive black holes (SMBHs) at their centres. They are known to show flux variation and this property can ...
  • The intermediate polar cataclysmic variable GK Persei 120 years after the nova explosion: a first dynamical mass study 
    Alvarez-Hernandez, A; Torre, M. A. P; Rodriguez-Gil, P; Shahbaz, T; Anupama, G. C; Gazeas, K. D; Pavana, M; Raj, A; Hakala, P; Stone, G; Gomez, S; Jonker, P. G; Ren, J.- J; Cannizzaro, G; Pastor-Marazuela, I; Goff, W; Corral-Santana, J. M; Sabo, R (Oxford University Press on behalf of Royal Astronomical Society, 2021-11)
    We present a dynamical study of the intermediate polar and dwarf nova cataclysmic variable GK Persei (Nova Persei 1901) based on a multisite optical spectroscopy and R-band photometry campaign. The radial velocity curve ...
  • Successive injection of opposite magnetic helicity: evidence for active regions without coronal mass ejections 
    Vemareddy, P (Oxford University Press on behalf of Royal Astronomical Society, 2021-11)
    Magnetic helicity (MH) is a measure of twist and shear of magnetic field. MH is injected in the active region (AR) corona through photospheric footpoint motions causing twisted and sheared magnetic fields. From the ...
