Flash from the Past: New Gamma-Ray Constraints on Light CP-even Scalar from SN1987A
Yue Yu, Writasree Maitra, P. S. Bhupal Dev +4
We derive new constraints on light CP-even scalars using old gamma-ray observations in the direction of SN1987A by the Solar Maximum Mission (SMM) satellite. Light scalars can be a…
Shock-induced chiral magnetic effect
Steven P. Harris, Srimoyee Sen
Weak-interaction-mediated chiral imbalance generation in idealized massless electrons during core-collapse supernovae was once proposed to be the source of strong magnetic fields f…
Bulk viscosity from neutron decays to dark baryons in neutron star matter
Steven P. Harris, C. J. Horowitz
The existence of a dark baryon that mixes with the neutron leads to the possibility of neutron decay into a dark sector. Such dark decays have been studied as possibly relevant for…
Symmetry energy expansion and the peak value of the bulk viscosity
Steven P Harris
The symmetry energy expansion is a useful way to parametrize the properties of dense matter near nuclear saturation density, and much work has been done to connect physical quantit…
Suppression of composition -modes in chemically-equilibrating warm neutron stars
Tianqi Zhao, Peter B. Rau, Alexander Haber +3
We investigate the impact of chemical equilibration and the resulting bulk viscosity on non-radial oscillation modes of warm neutron stars at temperatures up to MeV, r…
Bulk Viscosity in Dense Nuclear Matter
Steven P. Harris
In this chapter, I describe bulk viscosity as a general concept, and then focus on bulk viscosity in the dense matter present in compact objects. While this review is focused on bu…
Bulk viscosity of nuclear matter with pions in the neutrino-trapped regime
Steven P. Harris, Bryce Fore, Sanjay Reddy
Recent work [B. Fore and S. Reddy, Phys. Rev. C 101 035809 (2020)] has shown that the population of thermal pions could modify the equation of state and transport properties of hot…
New Constraints on Axion-Like Particles from IXPE Polarization Data for Magnetars
Ephraim Gau, Fazlollah Hajkarim, Steven P. Harris +4
We derive new constraints on axion-like particles (ALPs) using precision -ray polarization studies of magnetars. Specifically, we use the first detection of polarized -rays f…
