Disk-Like Matter Outflow from a Kerr-Type Wormhole: Possible Observational Manifestations and Magnetic Effects
Mikhail Piotrovich, Stanislava Buliga, Tinatin Natsvlishvili
We present a phenomenological study of a hypothetical compact object with a traversable 2 Kerr-type wormhole geometry connecting two asymptotically distinct regions. One mouth of t…
Estimation of black hole spins in low-mass AGNs and comparison with other types of AGNs
M. Yu. Piotrovich, S. D. Buliga, T. M. Natsvlishvili
We estimated the spins of a sample of 58 low-mass AGNs. Analysis of the obtained spins showed that they decrease with increasing SMBH mass, leading us to hypothesize that mergers a…
Red Quasars: Selecting Candidates in SDSS DR16 and Estimating Their Physical Parameters
M. Yu. Piotrovich, S. D. Buliga, T. M. Natsvlishvili
Using ''color cut'' method we obtained from SDSS DR16 catalog 733 red quasar candidates which amounted to approximately 4% of the objects from the initial sample. Then we estimated…
