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…
Spitzer Microlens Measurement of a Massive Remnant in a Well-Separated Binary
Y. Shvartzvald, A. Udalski, A. Gould +63
We report the detection and mass measurement of a binary lens OGLE-2015-BLG-1285La,b, with the more massive component having (80% probability). A main-sequence…
OGLE-2015-BLG-0479LA,B: Binary Gravitational Microlens Characterized by Simultaneous Ground-based and Space-based Observation
C. Han, A. Udalski, A. Gould +60
We present a combined analysis of the observations of the gravitational microlensing event OGLE-2015-BLG-0479 taken both from the ground and by the {\it Spitzer Space Telescope}. T…
Unification and physical interpretation of the radio spectra variability patterns in Fermi blazars and jet emission from NLSy1s
E. Angelakis, L. Fuhrmann, I. Nestoras +10
The F-GAMMA program is among the most comprehensive programs that aim at understanding the physics in active galactic nuclei through the multi-frequency monitoring of Fermi blazars…
On the Gerasimov-Drell-Hearn sum rule for the deuteron
H. Arenhoevel, G. Kress, R. Schmidt +1
The Gerasimov-Drell-Hearn sum rule is evaluated for the deuteron by explicit integration up to a photon energy of 550 MeV including contributions from the photodisintegration chann…
OGLE-2013-BLG-0911Lb: A Secondary on the Brown-Dwarf Planet Boundary around an M-dwarf
Shota Miyazaki, Takahiro Sumi, David P. Bennett +92
We present the analysis of the binary-lens microlensing event OGLE-2013-BLG-0911. The best-fit solutions indicate the binary mass ratio of q~0.03 which differs from that reported i…
