Stellar microlensing surveys as a probe of Primordial Black Holes: status and prospects
Anne M. Green
Stellar microlensing surveys are a powerful tool for probing dark matter in the form of planetary and stellar mass compact objects (COs), in particular primordial black holes (PBHs…
findAbar: how astronomers may perceive the bar in galaxies differently
Elizabeth J. Iles, Joss Bland-Hawthorn, Courtney Crawford +18
Bars are ubiquitous morphological features in the observed distribution of galaxies. There are similarly many methods for classifying these features and, without a strict theoretic…
The History of Primordial Black Holes
Bernard J. Carr, Anne M. Green
We overview the history of primordial black hole (PBH) research from the first papers around 50 years ago to the present epoch. The history may be divided into four periods, the di…
Primordial Black Hole stellar microlensing constraints: understanding their dependence on the density and velocity distributions
Anne M. Green
Microlensing surveys of stars in the Large Magellanic Cloud constrain the fraction of the Milky Way halo in Primordial Black Holes (PBHs) with mass $10^{-9} \lesssim M/M_{\odot} \l…
A Fast and Accurate Implementation of the Effective Fluid Approximation for Ultralight Axions
Adam Moss, Lauren Gaughan, Anne M. Green
We present a numerically efficient and accurate implementation of the Passaglia-Hu effective fluid approximation for ultralight axions (ULAs) within the Boltzmann code CAMB. This m…
How open is the asteroid-mass primordial black hole window?
Matthew Gorton, Anne M. Green
Primordial black holes (PBHs) can make up all of the dark matter (DM) if their mass, , is in the so-called 'asteroid-mass window', $10^{17} \, {\rm g} \lesssim m \lesssim 10^{22…
