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…
Spitzer Microlensing Program as a Probe for Globular Cluster Planets. Analysis of OGLE-2015-BLG-0448
Radosław Poleski, Wei Zhu, Grant W. Christie +83
The microlensing event OGLE-2015-BLG-0448 was observed by Spitzer and lay within the tidal radius of the globular cluster NGC 6558. The event had moderate magnification and was int…
Spitzer IRAC Photometry for Time Series in Crowded Fields
S. Calchi Novati, A. Gould, J. C. Yee +22
We develop a new photometry algorithm that is optimized for time series in crowded fields and that is particularly adapted to faint and/or heavily blended targets. We app…
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…
Mass Measurements of Isolated Objects from Space-based Microlensing
Wei Zhu, S. Calchi Novati, A. Gould +78
We report on the mass and distance measurements of two single-lens events from the 2015 \emph{Spitzer} microlensing campaign. With both finite-source effect and microlens parallax…
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…
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…
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…
A Venus-Mass Planet Orbiting a Brown Dwarf: Missing Link between Planets and Moons
A. Udalski, Y. K. Jung, C. Han +20
The co-planarity of solar-system planets led Kant to suggest that they formed from an accretion disk, and the discovery of hundreds of such disks around young stars as well as hund…
Fast radio bursts: the observational case for a Galactic origin
Dan Maoz, Abraham Loeb, Yossi Shvartzvald +10
There are by now ten published detections of fast radio bursts (FRBs), single bright GHz-band millisecond pulses of unknown origin. Proposed explanations cover a broad range from e…
Criteria for Sample Selection to Maximize Planet Sensitivity and Yield from Space-Based Microlens Parallax Surveys
Jennifer C. Yee, Andrew Gould, Charles Beichman +8
Space-based microlens parallax measurements are a powerful tool for understanding planet populations, especially their distribution throughout the Galaxy. However, if space-based o…
