  • 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 ...

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 ...
  • 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 ...

    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 ...
  • 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 ...
