The Maunakea Spectroscopic Explorer
Jennifer Marshall, James Bullock, Adam Burgasser +23
The Maunakea Spectroscopic Explorer is a next-generation massively multiplexed spectroscopic facility currently under development in Hawaii. It is completely dedicated to large-sca…
Discovery of a new Local Group Dwarf Galaxy Candidate in UNIONS: Boötes V
Simon E. T. Smith, Jaclyn Jensen, Joel Roediger +12
We present the discovery of Boötes V, a new ultra-faint dwarf galaxy candidate. This satellite is detected as a resolved overdensity of stars during an ongoing search for new Loca…
The APOGEE-2 Survey of the Orion Star Forming Complex: I. Target Selection and Validation with early observations
J'Neil Cottle, Kevin R. Covey, Genaro Suárez +26
The Orion Star Forming Complex (OSFC) is a central target for the APOGEE-2 Young Cluster Survey. Existing membership catalogs span limited portions of the OSFC, reflecting the diff…
Deep in the Fields of the Andromeda Halo: Discovery of the Pegasus VII dwarf galaxy in UNIONS
Simon E. T. Smith, Alan W. McConnachie, Stephen Gwyn +8
We present the newly discovered dwarf galaxy Pegasus VII (Peg VII), a member of the M31 sub-group which has been uncovered in the photometric catalogs from the Ultraviolet Nea…
The Pantheon+ Analysis: The Full Dataset and Light-Curve Release
Dan Scolnic, Dillon Brout, Anthony Carr +27
Here we present 1701 light curves of 1550 spectroscopically confirmed Type Ia supernovae (SNe Ia) that will be used to infer cosmological parameters as part of the Pantheon+ SN ana…
The Profile of the Galactic Halo from Pan-STARRS1 3 RR Lyrae
Nina Hernitschek, Judith G. Cohen, Hans-Walter Rix +11
We characterize the spatial density of the Pan-STARRS1 (PS1) sample of RR Lyrae stars, to study the properties of the old Galactic stellar halo as traced by RRab stars. This sample…
The discovery of the faintest known Milky Way satellite using UNIONS
Simon E. T. Smith, William Cerny, Christian R. Hayes +14
We present the discovery of Ursa Major III/UNIONS 1, the least luminous known satellite of the Milky Way, which is estimated to have an absolute V-band magnitude of $+2.2^{+0.4}_{-…
Absolute magnitudes and slope parameters for 250,000 asteroids observed by Pan-STARRS PS1 - preliminary results
Peter Vereš, Robert Jedicke, Alan Fitzsimmons +14
We present the results of a Monte Carlo technique to calculate the absolute magnitudes (H) and slope parameters (G) of about 240000 asteroids observed by the Pan-STARRS1 telescope…
The First High Redshift Quasar from Pan-STARRS
Eric Morganson, Gisella De Rosa, Roberto Decarli +13
We present the discovery of the first high redshift (z > 5.7) quasar from the Panoramic Survey Telescope and Rapid Response System 1 (Pan-STARRS1 or PS1). This quasar was initially…
The lowest of the low: discovery of SN 2019gsc and the nature of faint Iax supernovae
Shubham Srivastav, Stephen J. Smartt, Giorgos Leloudas +15
We present the discovery and optical follow-up of the faintest supernova-like transient known. The event (SN 2019gsc) was discovered in a star-forming host at 53\,Mpc by ATLAS. A d…
The Sloan Digital Sky Survey Reverberation Mapping Project: Sample Characterization
Yue Shen, Patrick B. Hall, Keith Horne +24
We present a detailed characterization of the 849 broad-line quasars from the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) project. Our quasar sample covers a redshift…
The Pantheon+ Analysis: Cosmological Constraints
Dillon Brout, Dan Scolnic, Brodie Popovic +43
We present constraints on cosmological parameters from the Pantheon+ analysis of 1701 light curves of 1550 distinct Type Ia supernovae (SNe Ia) ranging in redshift from t…
A Color-locus Method for Mapping Using Ensembles of Stars
Albert Lee, Gregory M. Green, Edward F. Schlafly +11
We present a simple but effective technique for measuring angular variation in across the sky. We divide stars from the Pan-STARRS1 catalog into Healpix pixels and determine…
