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…

Spins of SMBHs in distant low luminosity AGNs

M. Yu. Piotrovich, S. D. Buliga, T. M. Natsvlishvili

We estimated radiative efficiency, spin and SMBH mass values for sample of 33 distant low luminosity AGNs. The distribution of the estimated spin values (majority of objects have a…

Estimating the spins of supermassive black holes in distant ultraluminous quasars

M. Yu. Piotrovich, S. D. Buliga, T. M. Natsvlishvili

We estimated spin, inclination angle and corresponding SMBH mass values for sample of extremely distant (6 < z < 7.5) ultraluminous quasars. The estimated spin values are on averag…

Red quasars: estimation of SMBH spin, mass and accretion disk inclination angle

M. Yu. Piotrovich, S. D. Buliga, T. M. Natsvlishvili

We estimated values of spin, mass and inclination angle for sample of 42 red quasars. Our estimations show that 2 objects: F2MS~J1113+1244 and F2MS~J1434+0935 with highest Eddingto…

Search for Wormhole Candidates: Accreting Wormholes with Monopole Magnetic Fields

Mikhail Piotrovich, Serguei Krasnikov, Stanislava Buliga +1

The existence of even the simplest magnetized wormholes may lead to observable consequences. In the case where both the wormhole and the magnetic field around its mouths are static…
