An analysis of binary microlensing event OGLE-2015-BLG-0060

Y. Tsapras, A. Cassan, C. Ranc +83

We present the analysis of stellar binary microlensing event OGLE-2015-BLG-0060 based on observations obtained from 13 different telescopes. Intensive coverage of the anomalous par…

A measurement of the scintillation decay time constant of nuclear recoils in liquid xenon with the XMASS-I detector

XMASS Collaboration, K. Abe, K. Hiraide +35

We report an in-situ measurement of the nuclear recoil (NR) scintillation decay time constant in liquid xenon (LXe) using the XMASS-I detector at the Kamioka underground laboratory…

Search for dark matter in the form of hidden photons and axion-like particles in the XMASS detector

XMASS Collaboration, K. Abe, K. Hiraide +35

Hidden photons and axion-like particles are candidates for cold dark matter if they were produced non-thermally in the early universe. We conducted a search for both of these boson…

Ground-based parallax confirmed by Spitzer: binary microlensing event MOA-2015-BLG-020

Tianshu Wang, Wei Zhu, Shude Mao +83

We present the analysis of the binary gravitational microlensing event MOA-2015-BLG-020. The event has a fairly long timescale (about 63 days) and thus the light curve deviates sig…

Identification of Pb and Po in the bulk of copper samples with a low-background alpha particle counter

XMASS collaboration, K. Abe, K. Hiraide +39

We established a method to assay Pb and Po contaminations in the bulk of copper samples using a low-background alpha particle counter. The achieved sensitivity for…

A companion on the planet/brown dwarf mass boundary on a wide orbit discovered by gravitational microlensing

R. Poleski, A. Udalski, I. A. Bond +40

We present the discovery of a substellar companion to the primary host lens in the microlensing event MOA-2012-BLG-006. The companion-to-host mass ratio is 0.016, corresponding to…
