Dark Matter Capture in Supernovae Modifies Dark Photon Cooling Bounds
Aritra Gupta, Manibrata Sen
Core-collapse supernovae serve as powerful probes of light, weakly coupled particles, such as dark photons. The conventional SN1987A cooling bound constrains the dark photon mass-m…
Anomaly induced cooling of Neutron Stars: A Standard Model contribution
Sabyasachi Chakraborty, Aritra Gupta, Miguel Vanvlasselaer
Young neutron stars cool via the emission of neutrinos from their core. A precise understanding of all the different processes producing neutrinos in the hot and degenerate matter…
A closer look at the seesaw-dark matter correspondence
Rupert Coy, Aritra Gupta
In an earlier work, we showed that in very simple neutrino portal-like extensions of the Standard Model it is possible to achieve a one-to-one correspondence between dark matter ph…
Seesaw determination of the dark matter relic density
Rupert Coy, Aritra Gupta, Thomas Hambye
In this article, we show that in the usual type-I seesaw framework, augmented solely by a neutrino portal interaction, the dark matter (DM) relic density can be created through fre…
Observing the thermalization of dark matter in neutron stars
Raghuveer Garani, Aritra Gupta, Nirmal Raj
A promising probe to unmask particle dark matter is to observe its effect on neutron stars, the prospects of which depend critically on whether captured dark matter thermalizes in…
Dark matter capture in celestial objects: light mediators, self-interactions, and complementarity with direct detection
Basudeb Dasgupta, Aritra Gupta, Anupam Ray
We generalize the formalism for DM capture in celestial bodies to account for arbitrary mediator mass, and update the existing and projected astrophysical constraints on DM-nucleon…
