Astrophysical appearances of primordial black holes

Konstantin Postnov, Aleksandre Kuranov, Nikita Mitichkin

Interest to astrophysical evidence for primordial black holes (PBHs) formed in the early Universe from initial cosmological perturbations has increased after the discovery of coale…

Probing the nature of the X-ray source IGR J16327-4940 with Chandra

L. Sidoli, V. Sguera, K. Postnov +3

We report on the results of a Chandra observation of the source IGRJ16327-4940, suggested to be a high mass X-ray binary hosting a luminous blue variable star (LBV). The source fie…

Spectroscopic Searches for Evolutionary Orbital Period Changes in WR+OB Binaries: the case of V444 Cyg

I. Shaposhnikov, A. Cherepashchuk, A. Dodin +1

We present the results of new photometric and spectroscopic observations of WN5+O6 binary V444 Cyg and a detailed analysis of extant spectroscopy and photometry. Using elements of…

The first mm detection of a neutron star high-mass X-ray binary

J. van den Eijnden, L. Sidoli, M. Diaz Trigo +9

Neutron stars accreting from OB supergiants are often divided between persistently and transiently accreting systems, called Supergiant X-ray Binaries (SgXBs) and Supergiant Fast X…

Spectroscopic Searches for Evolutionary Orbital Period Changes in WR+OB Binaries: The case of CQ Cep and CX Cep

I. Shaposhnikov, A. Cherepashchuk, A. Dodin +1

We present the results of spectroscopic observations of two eclipsing WR+OB-type systems - CQ Cep and CX Cep, performed in 2020-2023 with a low-resolution slit spectrograph TDS ($λ…
