OGLE-2015-BLG-1395Lb: A Cold Sub-Saturn Mass Planet Orbiting an M Dwarf
Andrew A. Cole, Joshua W. Blackman, Jean-Philippe Beaulieu +75
We present an analysis of the high-magnification microlensing event OGLE-2015-BLG-1395 and report the discovery of a sub-Saturn mass companion to the lens. Photometric coverage of…
OGLE-2012-BLG-0563: Relative Proper Motion Constraint from Keck Follow-up finds the correct Lens
Aparna Bhattacharya, David P. Bennett, Jean Phillippe Beaulieu +11
We present Keck/NIRC2 adaptive optics imaging results of planetary microlensing event OGLE-2012-BLG-0563. We find that the OGLE-2012-BLG-0563L planetary system consists of a 1.12 +…
First Direct Identification of a Multi-Star Microlens System Hosting a Planet
Sean K. Terry, David P. Bennett, Jean-Philippe Beaulieu +11
Nearly 25 years have passed since gravitational microlensing delivered its first exoplanet discoveries. The relative proper motion between lens and source systems allows them to be…
An HST Wide Field Survey of the Galactic Bulge: Overview, Strategy, and First Results
Sean K. Terry, Jay Anderson, Charles A. Beichman +13
We present an HST imaging survey of a 1.1 sq. degree sky area toward the Milky Way Galactic Bulge. This field significantly overlaps with the upcoming Nancy Grace Roman Galactic Bu…
Historic microlensing events in the euclid Galactic Bulge Survey
V. Bozza, L. Salmeri, P. Rota +47
Microlensing campaigns have a long history of observations covering the Galactic bulge, where thousands of detections have been obtained, including many exoplanetary systems. The E…
TASSIE: a TASmanian Search for Inclined Exoplanets
T. Plunkett, A. A. Cole, J. P. Beaulieu +5
We present the first results of a pilot 'TASmanian Search for Inclined Exoplanets' (TASSIE) program. This includes observations and analysis of five short-period exoplanet candidat…
MOA-2010-BLG-328: Keck and HST Expose the Limits of Occams Razor in Microlensing
Aikaterini Vandorou, David P. Bennett, Jean-Philippe Beaulieu +7
We present high resolution follow-up data of the planetary microlensing event MOA-2010-BLG-328, using Keck and the Hubble. Keck data, taken 8 years after the event, reveal a strong…
OGLE-2014-BLG-1760: A Jupiter-Sun analogue residing in the Galactic Bulge
Natalia E. Rektsini, Clement Ranc, Naoki Koshimoto +11
We present the analysis of OGLE-2014-BLG-1760, a planetary system in the galactic bulge. We combine Keck Adaptive Optics follow-up observations in -band with re-reduced light cu…
Image-Constrained Modeling with Hubble and Keck Images Reveals that OGLE-2012-BLG-0563Lb is a Jupiter-Mass planet Orbiting a K Dwarf
David P. Bennett, Aparna Bhattacharya, Jean-Philippe Beaulieu +7
We present high angular resolution imaging from the {\sl Hubble Space Telescope} combined with adaptive optics imaging results from the {\sl Keck}-II telescope to determine the mas…
A Candidate High-Velocity Exoplanet System in the Galactic Bulge
Sean K. Terry, Jean-Philippe Beaulieu, David P. Bennett +11
We present an analysis of adaptive optics (AO) images from the Keck-I telescope of the microlensing event MOA-2011-BLG-262. The original discovery paper by Bennett et al. 2014 repo…
Finding planets via gravitational microlensing
Natalia E. Rektsini, Virginie Batista
Since the first microlensing planet discovery in 2003, more than 200 planets have been detected with gravitational microlensing, in addition to several free-floating planet and bla…
Unveiling MOA-2007-BLG-192: An M Dwarf Hosting a Likely Super-Earth
Sean K. Terry, Jean-Philippe Beaulieu, David P. Bennett +15
We present an analysis of high angular resolution images of the microlensing target MOA-2007-BLG-192 using Keck adaptive optics and the Hubble Space Telescope. The planetary host s…
Precise mass measurement of OGLE-2013-BLG-0132/MOA-2013-BLG-148: a Saturn mass planet orbiting an M-dwarf

We revisit the planetary microlensing event OGLE-2013-BLG-0132/MOA-2013-BLG-148 using Keck adaptive optics imaging in 2013 with NIRC2 and in 2020, 7.4 years after the event, with O…
ARES VI: Viability of one-dimensional retrieval models for transmission spectroscopy characterization of exo-atmospheres in the era of JWST and Ariel
Adam Yassin Jaziri, William Pluriel, Andrea Bocchieri +10
Observed exoplanet transit spectra are usually retrieved using 1D models to determine atmospheric composition while planetary atmospheres are 3D. With the JWST and future space tel…
