The eROSITA Final Equatorial Depth Survey (eFEDS): SDSS spectroscopic observations of X-ray sources
Catarina Aydar, Andrea Merloni, Tom Dwelly +45
We present one of the largest uniform optical spectroscopic surveys of X-ray selected sources to date that were observed as a pilot study for the Black Hole Mapper (BHM) survey. Th…
Linking black-hole growth with host galaxies: The accretion-stellar mass relation and its cosmic evolution
G. Yang, W. N. Brandt, F. Vito +9
Previous studies suggest that the growth of supermassive black holes (SMBHs) may be fundamentally related to host-galaxy stellar mass (). To investigate this SMBH growth-$…
Near Infrared Spectra and Intrinsic Luminosities of Candidate Type II Quasars at 2 < z < 3.4
Jenny E Greene, Rachael Alexandroff, Michael A Strauss +10
We present JHK near-infrared (NIR) spectroscopy of 25 candidate Type II quasars selected from the Sloan Digital Sky Survey, using Triplespec on the Apache Point Observatory 3.5m te…
The Data Release of the Sloan Digital Sky Survey-II Supernova Survey
Masao Sako, Bruce Bassett, Andrew C. Becker +46
This paper describes the data release of the Sloan Digital Sky Survey-II (SDSS-II) Supernova Survey conducted between 2005 and 2007. Light curves, spectra, classifications, and anc…
Very Low-mass Stellar and Substellar Companions to Solar-like Stars from MARVELS II: A Short-period Companion Orbiting an F Star with Evidence of a Stellar Tertiary And Significant Mutual Inclination
Scott W. Fleming, Jian Ge, Rory Barnes +59
We report the discovery via radial velocity of a short-period (P = 2.430420 \pm 0.000006 days) companion to the F-type main sequence star TYC 2930-00872-1. A long-term trend in the…
Ultraviolet and X-ray Variability of the Seyfert 1.5 Galaxy Markarian 817
Lisa M. Winter, Charles Danforth, Ranjan Vasudevan +9
We present an investigation of the ultraviolet and X-ray spectra of the Seyfert 1.5 galaxy Markarian 817. The ultraviolet analysis includes two recent observations taken with the C…
MARVELS-1b: A Short-Period, Brown Dwarf Desert Candidate from the SDSS-III MARVELS Planet Search
Brian L. Lee, Jian Ge, Scott W. Fleming +59
We present a new short-period brown dwarf candidate around the star TYC 1240-00945-1. This candidate was discovered in the first year of the Multi-object APO Radial Velocity Exopla…
A Measurement of the Rate of Type Ia Supernovae in Galaxy Clusters from the SDSS-II Supernova Survey
Benjamin Dilday, Bruce Bassett, Andrew Becker +32
ABRIDGED We present measurements of the Type Ia supernova (SN) rate in galaxy clusters based on data from the Sloan Digital Sky Survey-II (SDSS-II) Supernova Survey. The cluster SN…
Type II-P Supernovae from the SDSS-II Supernova Survey and the Standardized Candle Method
Chris B. D'Andrea, Masao Sako, Benjamin Dilday +24
We apply the Standardized Candle Method (SCM) for Type II Plateau supernovae (SNe II-P), which relates the velocity of the ejecta of a SN to its luminosity during the plateau, to 1…
The First Data Release of the Sloan Digital Sky Survey
The SDSS collaboration, Kevork Abazajian
The Sloan Digital Sky Survey has validated and made publicly available its First Data Release. This consists of 2099 square degrees of five-band (u, g, r, i, z) imaging data, 186,2…
LOTIS, Super-LOTIS, SDSS and Tautenburg Observations of GRB 010921
H. S. Park, G. G. Williams, D. H. Hartmann +36
We present multi-instrument optical observations of the High Energy Transient Explorer (HETE-2)/Interplanetary Network (IPN) error box of GRB 010921. This event was the first gamma…
The Ghost of Sagittarius and Lumps in the Halo of the Milky Way
Heidi Jo Newberg, Brian Yanny, Constance M. Rockosi +16
We identify new structures in the halo of the Milky Way Galaxy from positions, colors and magnitudes of five million stars detected in the Sloan Digital Sky Survey. Most of these s…
Galaxy Number Counts from the Sloan Digital Sky Survey Commissioning Data
