MOA 2011-BLG-028Lb: a Neptune-mass Microlensing Planet in the Galactic Bulge
J. Skowron, A. Udalski, R. Poleski +35
We present the discovery of a Neptune-mass planet orbiting a 0.8 +- 0.3 M_Sun star in the Galactic bulge. The planet manifested itself during the microlensing event MOA 2011-BLG-02…
Campaign 9 of the Mission: Observational Parameters, Scientific Drivers, and Community Involvement for a Simultaneous Space- and Ground-based Microlensing Survey
Calen B. Henderson, Radosław Poleski, Matthew Penny +118
's Campaign 9 (C9) will conduct a 3.7 deg survey toward the Galactic bulge from 7/April through 1/July of 2016 that will leverage the spatial separation between…
The First Neptune Analog or Super-Earth with Neptune-like Orbit: MOA-2013-BLG-605Lb
T. Sumi, A. Udalski, D. P. Bennett +46
We present the discovery of the first Neptune analog exoplanet or super-Earth with Neptune-like orbit, MOA-2013-BLG-605Lb. This planet has a mass similar to that of Neptune or a su…
Red noise versus planetary interpretations in the microlensing event OGLE-2013-BLG-446
E. Bachelet, D. M. Bramich, C. Han +98
For all exoplanet candidates, the reliability of a claimed detection needs to be assessed through a careful study of systematic errors in the data to minimize the false positives r…
MOA-2010-BLG-353Lb A Possible Saturn Revealed
N. J. Rattenbury, D. P. Bennett, T. Sumi +30
We report the discovery of a possible planet in microlensing event MOA-2010-BLG-353. This event was only recognised as having a planetary signal after the microlensing event had fi…
The frequency of snowline-region planets from four-years of OGLE-MOA-Wise second-generation microlensing
Y. Shvartzvald, D. Maoz, A. Udalski +35
We present a statistical analysis of the first four seasons from a "second-generation" microlensing survey for extrasolar planets, consisting of near-continuous time coverage of 8…
Spitzer Parallax of OGLE-2015-BLG-0966: A Cold Neptune in the Galactic Disk
R. A. Street, A. Udalski, S. Calchi Novati +106
We report the detection of a Cold Neptune m_planet=21+/-2MEarth orbiting a 0.38MSol M dwarf lying 2.5-3.3 kpc toward the Galactic center as part of a campaign combining ground-base…
The Search for >35 MeV Neutrons from the June 3, 2012 Impulsive Flare
K. Koga, S. Masuda, H. Matsumoto +5
We analyzed a highly impulsive solar flare observed on June 3, 2012. In association with this flare, emissions of hard X-rays, high-energy gamma rays, and neutrons were detected by…
Results of a Measurement of Solar Neutrons Emitted on March 5, 2012 using a Fiber-type neutron monitor onboard the SEDA-AP attached to the ISS
K. Koga, H. Matsumoto, O. Okudaira +6
The solar neutron detector SEDA-FIB onboard the International Space Station (ISS) has detected several events from the solar direction associated with three large solar flares obse…
Simultaneous Observation of Solar Neutrons from the ISS and High Mountain Observatories in association with a flare on July 8, 2014
Y. Muraki, D. Lopez, K. Koga +17
An M6.5-class flare was observed at N12E56 of the solar surface at 16:06 UT on July 8, 2014. In association with this flare, solar neutron detectors located on two high mountains,…
Planet Sensitivity from Combined Ground- and Space-based Microlensing Observations
Wei Zhu, Andrew Gould, Charles Beichman +45
To move one step forward toward a Galactic distribution of planets, we present the first planet sensitivity analysis for microlensing events with simultaneous observations from spa…
Measurements of longitudinal and transverse momentum distributions for neutral pions in the forward-rapidity region with the LHCf detector
O. Adriani, E. Berti, L. Bonechi +25
The differential cross sections for inclusive neutral pions as a function of transverse and longitudinal momentum in the very forward rapidity region have been measured at the Larg…
OGLE-2012-BLG-0563Lb: a Saturn-mass Planet around an M Dwarf with the Mass Constrained by Subaru AO imaging
A. Fukui, A. Gould, T. Sumi +58
We report the discovery of a microlensing exoplanet OGLE-2012-BLG-0563Lb with the planet-star mass ratio ~1 x 10^{-3}. Intensive photometric observations of a high-magnification mi…
MOA-2007-BLG-197: Exploring the brown dwarf desert
C. Ranc, A. Cassan, M. D. Albrow +48
We present the analysis of MOA-2007-BLG-197Lb, the first brown dwarf companion to a Sun-like star detected through gravitational microlensing. The event was alerted and followed-up…
Measurement of very forward neutron energy spectra for 7 TeV proton--proton collisions at the Large Hadron Collider
O. Adriani, E. Berti, L. Bonechi +28
The Large Hadron Collider forward (LHCf) experiment is designed to use the LHC to verify the hadronic-interaction models used in cosmic-ray physics. Forward baryon production is on…
