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…

Formation of twin compact stars in low-mass X-ray binaries: Implications on eccentric and isolated millisecond pulsar populations
S. Chanlaridis, D. Ohse, D. E. Alvarez-Castillo +5
Millisecond pulsars (MSPs) are laboratories for stellar evolution, strong gravity, and ultra-dense matter. Although MSPs are thought to originate in low-mass X-ray binaries (LMXBs)…

Type Ia supernovae from non-accreting progenitors
John Antoniadis, Savvas Chanlaridis, Götz Gräfener +1
Type Ia supernovae (SNe Ia) are manifestations of stars deficient of hydrogen and helium disrupting in a thermonuclear runaway. While explosions of carbon-oxygen white dwarfs are t…
