The 3D-HST Survey: Hubble Space Telescope WFC3/G141 grism spectra, redshifts, and emission line measurements for galaxies
Ivelina G. Momcheva, Gabriel B. Brammer, Pieter G. van Dokkum +27
We present reduced data and data products from the 3D-HST survey, a 248-orbit HST Treasury program. The survey obtained WFC3 G141 grism spectroscopy in four of the five CANDELS fie…
Cold gas and a Milky Way-type 2175 Å bump in a metal-rich and highly depleted absorption system
Jingzhe Ma, Paul Caucal, Pasquier Noterdaeme +9
We report the detection of a strong Milky Way-type 2175 Å extinction bump at = 2.1166 in the quasar spectrum towards SDSS J121143.42+083349.7 from the Sloan Digital Sky Surv…
The SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Overview and Early Data
Kyle S. Dawson, Jean-Paul Kneib, Will J. Percival +143
The Extended Baryon Oscillation Spectroscopic Survey (eBOSS) will conduct novel cosmological observations using the BOSS spectrograph at Apache Point Observatory. Observations will…
Magellan LDSS3 emission confirmation of galaxies hosting metal-rich Lyman-alpha absorption systems
Lorrie A. Straka, Sean D. Johnson, Donald G. York +5
Using the Low Dispersion Survey Spectrograph 3 at the Magellan II Clay Telescope, we target {candidate absorption host galaxies} detected in deep optical imaging {(reaching limitin…
The SDSS-IV in 2014: A Demographic Snapshot
Britt Lundgren, Karen Kinemuchi, Gail Zasowski +8
Many astronomers now participate in large international collaborations, and it is important to examine whether these structures foster a scientific climate that is inclusive and di…
