The Abundance of Clustered Primordial Black Holes from Quasar Microlensing
Sven Heydenreich, Evencio Mediavilla, Jorge Jiménez-Vicente +2
While elementary particles are the favored candidate for the elusive dark matter, primordial black holes (PBHs) have also been considered to fill that role. Gravitational microlens…
Abundance of LIGO/Virgo Black Holes from Microlensing Observations of Quasars with Reverberation Mapping Size Estimates
A. Esteban-Gutiérrez, E. Mediavilla, J. Jiménez-Vicente +3
Assuming a population of Black Holes (BHs) with masses in the range inferred by LIGO/Virgo from BH mergers, we use quasar microlensing observations to estimate their abundances. We…
Limiting the Abundance of LIGO/Virgo Black Holes with Microlensing Observations of Quasars of Finite Size
A. Esteban-Gutiérrez, E. Mediavilla, J. Jiménez-Vicente +3
We present a simple but general argument that strongly limits the abundance of Primordial Black Holes (PBHs) (or other unknown population of compact objects) with masses similar to…
The Impact of the Mass Spectrum of Lenses in Quasar Microlensing Studies. Constraints on a Mixed Population of Primordial Black Holes and Stars
A. Esteban-Gutiérrez, N. Agües-Paszkowsky, E. Mediavilla +3
We show that quasar microlensing magnification statistics induced by a population of point microlenses distributed according to a mass-spectrum can be very well approximated by tha…
