We report the discovery of a very cool brown dwarf, ULAS J003402.77-005206.7 (ULAS J0034-00), identified in the UKIRT Infrared Deep Sky Survey First Data...
A wealth of new planetary nebulae from the IPHAS survey
We report on the current status of the search for planetary nebulae (PNe) in the IPHAS survey, the 1800 square degree H-alpha survey of the Northern Galactic...
Abundances, Stellar Parameters, and Spectra from the SDSS-III/APOGEE Survey
The SDSS-III/Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey operated from 2011–2014 using the APOGEE spectrograph, which collects high...
The OSIRIS Tunable Emission Line Object survey (OTELO) will provide a deep, complete sample of active galactic nuclei (AGN), and able to separate them...
The Advanced Large Homogeneous Area Medium Band Redshift Astronomical (ALHAMBRA) survey is a photometric survey designed to study systematically cosmic...
Aligned, Multiple-transient Events in the First Palomar Sky Survey
Old, digitized astronomical images taken before the human spacefaring age offer a rare glimpse of the sky before the era of artificial satellites. In this paper...
An absolute calibration of DENIS (deep near infrared southern sky survey)
An absolute calibration of the DENIS photometric system is presented. It includes the determination of the overall transmission profiles in the 3 bands, namely...
An Intermediate-age Alpha-rich Galactic Population in K2
We explore the relationships between the chemistry, ages, and locations of stars in the Galaxy using asteroseismic data from the K2 mission and spectroscopic...
Anomalously Low-metallicity Regions in MaNGA Star-forming Galaxies: Accretion Caught in Action?
We use data from 1222 late-type star-forming galaxies in the SDSS IV Mapping Nearby Galaxies at Apache Point Observatory survey to identify regions in which the...
