A Pan-STARRS1 View of the Bifurcated Sagittarius Stream
C. T. Slater, E. F. Bell, E. F. Schlafly +12
We use data from the Pan-STARRS1 survey to present a panoramic view of the Sagittarius tidal stream in the southern Galactic hemisphere. As a result of the extensive sky coverage o…
Is the 130 GeV Line Real? A Search for Systematics in the Fermi-LAT Data
Douglas P. Finkbeiner, Meng Su, Christoph Weniger
Our recent claims of a Galactic center feature in Fermi-LAT data at approximately 130 GeV have prompted an avalanche of papers proposing explanations ranging from dark matter annih…
Double Gamma-ray Lines from Unassociated Fermi-LAT Sources
Meng Su, Douglas P. Finkbeiner
Gamma ray emission from dark matter subhalos in the Milky Way has long been sought as a sign of dark matter particle annihilation. So far, searches for gamma-ray continuum from sub…
Strong Evidence for Gamma-ray Line Emission from the Inner Galaxy
Meng Su, Douglas P. Finkbeiner
Using 3.7 years of \Fermi-LAT data, we examine the diffuse 80-200 GeV emission in the inner Galaxy and find a resolved gamma-ray feature at GeV. We model the spatial…
Evidence for Gamma-ray Jets in the Milky Way
Meng Su, Douglas P. Finkbeiner
Although accretion onto supermassive black holes in other galaxies is seen to produce powerful jets in X-ray and radio, no convincing detection has ever been made of a kpc-scale je…
The Metallicity of the Monoceros Stream
Aaron M. Meisner, Anna Frebel, Mario Juric +1
We present low-resolution MMT Hectospec spectroscopy of 594 candidate Monoceros stream member stars. Based on strong color-magnitude diagram overdensities, we targeted three fields…
The DEEP2 Galaxy Redshift Survey: Design, Observations, Data Reduction, and Redshifts
Jeffrey A. Newman, Michael C. Cooper, Marc Davis +31
We describe the design and data sample from the DEEP2 Galaxy Redshift Survey, the densest and largest precision-redshift survey of galaxies at z ~ 1 completed to date. The survey h…
Photometric Calibration of the First 1.5 Years of the Pan-STARRS1 Survey
E. F. Schlafly, D. P. Finkbeiner, M. Juric +14
We present a precise photometric calibration of the first 1.5 years of science imaging from the Pan-STARRS1 survey (PS1), an ongoing optical survey of the entire sky north of decli…
