DOI: 10.1088/1475-7516/2025/01/052
Abstract: Linear scalar cosmological perturbations have increasing spectra in the contracting phase of bouncing models. We study the conditions for which these perturbations may collapse into primordial black holes and the hypothesis that these objects constitute… read more here.

DOI: 10.1097/md.0000000000014230
Abstract: Rationale: An idiopathic macular hole that causes substantial reduction in central visual acuity is believed to involve no obvious underlying diseases; thus, it is suspected to form due to the presence of idiopathic tractional forces… read more here.

DOI: 10.1097/md.0000000000021835
Abstract: Abstract Rationale: Macular hole (MH) formation after vitrectomy is rare and it may be due to several mechanisms associated with change of foveolar anatomy by vitrectomy. If a MH develops after vitrectomy, surgical treatments including… read more here.

DOI: 10.1103/physrevd.111.083521
Abstract: We revisit the question of how generic is the formation of primordial black holes via self-resonant growth of inflaton fluctuations in the post-inflationary, preheating phase. Using analytical and lattice calculations, we find that primordial black… read more here.

DOI: 10.1103/physrevlett.133.081401
Abstract: We provide evidence for a correspondence between the formation of black holes and the stability of circular null geodesics around the collapsing perturbation. We first show that the critical threshold of the compaction function to… read more here.
