NICER X-ray Observations of Seven Nearby Rotation-Powered Millisecond Pulsars
S. Guillot, M. Kerr, P. S. Ray +18
NICER observed several rotation-powered millisecond pulsars to search for or confirm the presence of X-ray pulsations. When broad and sine-like, these pulsations may indicate therm…
Constraining the Local Burst Rate Density of Primordial Black Holes with HAWC
A. Albert, R. Alfaro, C. Alvarez +84
Primordial Black Holes (PBHs) may have been created by density fluctuations in the early Universe and could be as massive as solar masses or as small as the Planck mass. I…
