Solar-cycle variations in meridional flows and rotational shear within the Sun's near-surface shear layer

Anisha Sen, S. P. Rajaguru, Abhinav Govindan Iyer +3

Using solar-cycle long helioseismic measurements of meridional and zonal flows in the near-surface shear layer (NSSL) of the Sun, we study their spatio-temporal variations and conn…

Gravitational Spectra and Wave Propagation in Regular Black Holes Supported by a Dehnen Halo

Bekir Can Lütfüoğlu, Abubakir Shermatov, Javlon Rayimbaev +2

We investigate gravitational perturbations, quasinormal modes, grey-body factors, and absorption cross-sections of the recently proposed regular and asymptotically flat black hole…

Gravitational quasinormal modes of Dymnikova black holes

Bekir Can Lütfüoğlu, Erdinç Ulaş Saka, Abubakir Shermatov +3

We investigate gravitational quasinormal modes of the Dymnikova black hole, a regular spacetime in which the central singularity is replaced by a de Sitter core. This geometry, ori…

New analytical model of rotating black hole with dark matter halo: constraints from EHT observations and accretion disk

Uktamjon Uktamov, Sanjar Shaymatov, Bobomurat Ahmedov +1

In this paper, we start from a static black hole (BH) immersed in a Deanne-type dark matter (DM) halo and employ the Newman-Janis algorithm (NJA) to generate the rotating black hol…
