Spectrophotometric parallaxes with linear models: Accurate distances for luminous red-giant stars

David W. Hogg, Anna-Christina Eilers, Hans-Walter Rix

With contemporary infrared spectroscopic surveys like APOGEE, red-giant stars can be observed to distances and extinctions at which Gaia parallaxes are not highly informative. Yet…

The Circular Velocity Curve of the Milky Way from to kpc

Anna-Christina Eilers, David W. Hogg, Hans-Walter Rix +1

We measure the circular velocity curve of the Milky Way with the highest precision to date across Galactocentric distances of kpc. Our analysis dra…

The Opacity of the Intergalactic Medium Measured Along Quasar Sightlines at

Anna-Christina Eilers, Frederick B. Davies, Joseph F. Hennawi

We publicly release a new sample of medium resolution quasar spectra at observed with the Echellette Spectrograph and Imager (ESI) on the Keck te…

First Spectroscopic Study of a Young Quasar

Anna-Christina Eilers, Joseph F. Hennawi, Frederick B. Davies

The quasar lifetime is one of the most fundamental quantities for understanding quasar evolution and the growth of supermassive black holes (SMBHs), but remains uncert…

The Role of Galaxies and AGN in Reionising the IGM - I: Keck Spectroscopy of 5 < z < 7 Galaxies in the QSO Field J1148+5251

Koki Kakiichi, Richard S. Ellis, Nicolas Laporte +7

We introduce a new method for determining the influence of galaxies and active galactic nuclei (AGN) on the physical state of the intergalactic medium (IGM) at high redshift and il…
