Abstract Primordial black holes (PBHs) could explain some fraction of dark matter and shed light on many areas early-Universe physics. Despite over half a century research interest, PBH population has so far eluded detection. The most competitive constraints the comprised PBHs ( f DM ) in (10 −9 –10) M ⊙ mass ranges come from photometric microlensing bound ≲ 10 −2 –10 −1 . With advent Roman Space Telescope with its submilliarcsecond astrometric capabilities planned Galactic Bulge Time Domain...
Primordial Black Holes (PBHs) could explain some fraction of dark matter and shed light on many areas early-universe physics. Despite over half a century research interest, PBH population has so far eluded detection. The most competitive constraints the comprised PBHs ($f_{\rm DM}$) in $(10^{-9}-10)M_{\odot}$ mass-ranges come from photometric microlensing bound $f_{\rm DM}\lesssim10^{-2}-10^{-1}$.
