X-ray observations of the Intermediate Polar TX Col
Jeewan Chandra Pandey, Nikita Rawat, Srinivas M. Rao +2
We present the timing analysis of the intermediate polar TX Col in the X-ray band using the observations made by Chandra, Swift, and Suzaku during the years 2000, 2007, and 2009, r…
Observational properties of a bright type Iax SN 2018cni and a faint type Iax SN 2020kyg
Mridweeka Singh, Devendra. K. Sahu, Raya Dastidar +29
We present the optical photometric and spectroscopic analysis of two type Iax SNe 2018cni and 2020kyg. SN 2018cni is a bright type Iax SN (M = 17.810.21 mag) whe…
Unravelling optical and X-ray properties of the disc-dominated intermediate polar IGR J15094-6649
Arti Joshi, Nikita Rawat, Axel Schwope +5
We present analyses of an Intermediate Polar, IGR J15094-6649, based on the archival optical data obtained from the Transiting Exoplanet Survey Satellite (TESS) and X-ray data obta…
SWIFT J0503.7-2819: A nearly synchronous intermediate polar below the period gap?
Nikita Rawat, J. C. Pandey, Arti Joshi +2
Based on the X-ray observations from XMM-Newton and Swift, and optical observations from Transiting Exoplanet Survey Satellite (TESS) and AAVSO, we present temporal and spectral pr…
Authenticating the Presence of a Relativistic Massive Black Hole Binary in OJ 287 Using its General Relativity Centenary Flare: Improved Orbital Parameters
Lankeswar Dey, M. J. Valtonen, A. Gopakumar +5
Results from regular monitoring of relativistic compact binaries like PSR 1913+16 are consistent with the dominant (quadrupole) order emission of gravitational waves (GWs). We show…
Primary black hole spin in OJ287 as determined by the General Relativity centenary flare
M. J. Valtonen, S. Zola, S. Ciprini +87
OJ287 is a quasi-periodic quasar with roughly 12 year optical cycles. It displays prominent outbursts which are predictable in a binary black hole model. The model predicted a majo…
