On 17 August 2017, Swope Supernova Survey 2017a (SSS17a) was discovered as the
optical counterpart of the binary neutron star gravitational wave event GW170817. We report …

We present spectroscopic data for individual stars observed from 2004 March through 2008
August as part of our Michigan/MIKE Fiber System (MMFS) survey of four dwarf spheroidal …

This paper presents a newly established sample of 19 unique galaxies and galaxy groups at
redshift z= 0.89–1.21 in six QSO fields from the Cosmic Ultraviolet Baryon Survey (CUBS) …

Accurate photometric redshifts are among the key requirements for precision weak lensing
measurements. Both the large size of the Sloan Digital Sky Survey (SDSS) and the …

Motivated by spectroscopic confirmation of three overdense regions in the COSMOS field at
z∼ 3.35, we analyse the uniquely deep multiwavelength photometry and extensive …

We present the first results of our optical spectroscopy program aimed to provide redshifts
and identifications for the X-ray sources in the Extended Chandra Deep Field South. A total …

We present optical integral field unit (IFU) observations (VLT/VIMOS-IFU and
WIYN/SparsePak), and associated archival deep Hα imaging (MPG/ESO 2.2 m WFI), of the …

This is the second part of an Hα kinematics follow-up survey of the Spitzer Infrared Nearby
Galaxies Survey (SINGS) sample. The aim of this paper is to shed new light on the role of …

Weak gravitational lensing is a valuable probe of galaxy formation and cosmology. Here we
quantify the effects of using photometric redshifts (photo-z) in galaxy–galaxy lensing, for both …

We use photometric and spectroscopic observations of the eclipsing binary V69-47 Tuc to
derive the masses, radii, and luminosities of the component stars. Based on measured …
