We study the thermodynamical features and dynamical evolutions of various apparent horizons associated with the Vaidya evaporating black hole surrounded by the cosmological fields of dust, radiation, quintessence, cosmological constant-like and phantom. In this regard, we address in detail how do these surrounding fields contribute to the characteristic features of a surrounded dynamical black hole in comparison to a dynamical black hole in an empty background.

  1. Shadow of the generalized Vaidya black hole

    gr-qc 2026-07 conditional novelty 5.0 of 10

    For self-similar Husain black holes, the barotropic index α controls the shadow: α<1/2 enlarges it, α>1/2 shrinks it, with a quasistatic influx criterion for the time-dependent case.

  2. Barotropic Equation of State and Nonlinear Electrodynamics in Dynamical Black Hole Spacetimes

    gr-qc 2025-04 reject novelty 4.0 of 10

    The paper's identification of the Husain solution's integration constant with nonlinear electrodynamics charges is undermined by internal inconsistencies in the reconstruction.

  3. Gravitational Collapse and Formation of Regular Black Holes: Dymnikova, Hayward, and Beyond

    gr-qc 2025-04 reject novelty 4.0 of 10

    The paper derives a radiation density formula for a collapse in which baryonic matter converts into arbitrary target regular black hole matter.
