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…
Extremely metal-poor stars from the cosmic dawn in the bulge of the Milky Way
L. M. Howes, A. R. Casey, M. Asplund +22
The first stars are predicted to have formed within 200 million years after the Big Bang, initiating the cosmic dawn. A true first star has not yet been discovered, although stars…
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…
Interstellar Extinction Curve Variations Toward the Inner Milky Way: A Challenge to Observational Cosmology
David M. Nataf, Oscar A. Gonzalez, Luca Casagrande +18
We investigate interstellar extinction curve variations toward 4 deg of the inner Milky Way in photometry from the OGLE-III and surveys, with supportin…
The Controversial Star-Formation History and Helium Enrichment of the Milky Way Bulge
David M. Nataf
The stellar population of the Milky Way bulge is thoroughly studied, with a plethora of measurements from virtually the full suite of instruments available to astronomers. It is th…
A high-velocity bulge RR Lyrae variable on a halo-like orbit
Andrea Kunder, R. Michael Rich, Keith Hawkins +21
We report on the RR Lyrae variable star, MACHO 176.18833.411, located toward the Galactic bulge and observed within the data from the ongoing Bulge RR Lyrae Radial Velocity Assay (…
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…
The GALAH Survey: Scientific Motivation
G. M. De Silva, K. C. Freeman, J. Bland-Hawthorn +44
The GALAH survey is a large high-resolution spectroscopic survey using the newly commissioned HERMES spectrograph on the Anglo-Australian Telescope. The HERMES spectrograph provide…
Uncertainties in The Interstellar Extinction Curve and the Cepheid Distance to M101
David M. Nataf
I revisit the Cepheid-distance determination to the nearby spiral galaxy M101 (Pinwheel Galaxy) of Shappee & Stanek (2011), in light of several recent investigations questioning th…
