Vortex Creep Heating vs. Dark Matter Heating in Neutron Stars
Motoko Fujiwara, Koichi Hamaguchi, Natsumi Nagata +1
Dark matter particles captured in neutron stars deposit their energy as heat. This DM heating effect can be observed only if it dominates over other internal heating effects in NSs…
Vortex Creep Heating in Neutron Stars
Motoko Fujiwara, Koichi Hamaguchi, Natsumi Nagata +1
Recent observations of old warm neutron stars suggest the presence of a heating source in these stars, requiring a paradigm beyond the standard neutron-star cooling theory. In this…
Exploring the dark sectors via the cooling of white dwarfs
Jaime Hoefken Zink, Maura E. Ramirez-Quezada
As dense and hot bodies with a well-understood equation of state, white dwarfs offer a unique opportunity to investigate new physics. In this paper, we examine the role of dark sec…
Thermal Leptogenesis in the Minimal Gauged Model
Alessandro Granelli, Koichi Hamaguchi, Natsumi Nagata +2
We discuss the thermal leptogenesis mechanism within the minimal gauged U(1) model to explain the observed baryon asymmetry of the Universe (BAU). In such framework, th…
Light scalar explanation for 18 TeV GRB 221009A
Shyam Balaji, Maura E. Ramirez-Quezada, Joseph Silk +1
Recent astrophysical transient Swift J1913.1+1946 may be associated with the -ray burst GRB 221009A. The redshift of this event is . Very high-energy -rays (up…
