Many Mergers Might Fill the Mass Gap
Did you know that many observed black holes theoretically shouldn’t exist? Today’s paper gathers gravitational wave evidence for how these impossible black holes might have formed.
Deblurring the Dark Compact Object Picture with Microlensing
Lenses aren’t always made of glass, sometimes they’re made of dark matter compact objects! Today’s paper explores if and how we can tell primordial black holes apart from dark black holes using gravitational microlensing measurements.
Neutri-yes or Neutri-no: Could Magnetars Explain Two Mysteries of the Universe?
Today’s bite explores if highly magnetic compact objects called magnetars could explain where the observed background of high-energy neutrinos in our Universe comes from!
