Searches for signatures of ultra-light axion dark matter in polarimetry data of the European Pulsar Timing Array
N. K. Porayko, P. Usynina, J. Terol-Calvo +74
Ultra-light axion-like particles (ALPs) can be a viable solution to the dark matter problem. The scalar field associated with ALPs, coupled to the electromagnetic field, acts as an…
Stripping of a neutron star in a close binary system in a pair with a black hole
Nikita Kramarev, Alexander Kuranov, Andrey Yudin +1
We consider the final evolutionary stages of a neutron star-black hole pair. According to the current paradigm, such systems eventually coalesce, which in some cases is accompanied…
Revealing the state transition of Cen X-3 at high spectral resolution with Chandra
Graciela Sanjurjo-Ferrín, Jose Miguel Torrejón, Lida Oskinova +4
Cen X-3 is a compact, high-mass X-ray binary (HMXRB), likely powered by Roche lobe overflow. We present a phase-resolved X-ray spectral and timing analysis of a target of opportuni…
Primordial Intermediate-mass Binary Black Holes as Targets for Space Laser Interferometers
Konstantin Postnov, Ilya Chekh
Primordial black holes (PBHs) with log-normal mass spectrum with masses up to can be created after QCD phase transition in the early Universe at $z\sim 10^…
Optical Identification and Spectroscopic Redshift Measurements of 216 Galaxy Clusters from the SRG/eROSITA All-Sky Survey
I. A. Zaznobin, R. A. Burenin, A. A. Belinski +34
We present the results of the optical identification and spectroscopic redshift measurements of 216 galaxy clusters detected in the SRG/eROSITA all-sky X-ray survey. The spectrosco…
Spectroscopic Searches for Evolutionary Orbital Period Changes in WR+OB Binaries: the Case of WR 127 (Hen 3-1772)
I. A. Shaposhnikov, A. M. Cherepashchuk, A. V. Dodin +1
We aim at searching for secular evolution of the orbital period in the short-period binary system WR 127 (WN3b+O9.5V, ). We performed new low-resolution spectroscopic…
