Constraints on Earth-mass primordial black holes from OGLE 5-year microlensing events
Hiroko Niikura, Masahiro Takada, Shuichiro Yokoyama +2
We constrain the abundance of primordial black holes (PBH) using 2622 microlensing events obtained from 5-years observations of stars in the Galactic bulge by the Optical Gravitati…
The Hyper Suprime-Cam SSP Survey: Overview and Survey Design
H. Aihara, N. Arimoto, R. Armstrong +139
Hyper Suprime-Cam (HSC) is a wide-field imaging camera on the prime focus of the 8.2m Subaru telescope on the summit of Maunakea in Hawaii. A team of scientists from Japan, Taiwan…
Microlensing constraints on primordial black holes with the Subaru/HSC Andromeda observation
Hiroko Niikura, Masahiro Takada, Naoki Yasuda +8
Primordial black holes (PBHs) have long been suggested as a viable candidate for the elusive dark matter (DM). The abundance of such PBHs has been constrained using a number of ast…
Modifications to the Etherington Distance Duality Relation and Observational Limits
Surhud More, Hiroko Niikura, Jonas Schneider +2
The Etherington distance duality relation, which relates the luminosity distance, the angular diameter distance and the redshift of objects, depends only upon a conservation law fo…
Detection of universality of dark matter profile from Subaru weak lensing measurements of 50 massive clusters
Hiroko Niikura, Masahiro Takada, Nobuhiro Okabe +2
We develop a novel method of measuring the lensing distortion profiles of clusters with stacking the scaled amplitudes of background galaxy ellipticities as a function of the scale…
