A possible bright ultraviolet flash from a galaxy at redshift z ~ 11
Linhua Jiang, Shu Wang, Bing Zhang +8
In the optical sky, minutes-duration transients from cosmological distances are rare. Known objects that give rise to such transients include gamma-ray bursts (GRBs), the most lumi…
Evidence for GN-z11 as a luminous galaxy at redshift 10.957

Revisiting the HD 21749 Planetary System with Stellar Activity Modeling
Tianjun Gan, Sharon Xuesong Wang, Johanna K. Teske +26
HD 21749 is a bright ( mag) K dwarf at 16 pc known to host an inner terrestrial planet HD 21749c as well as an outer sub-Neptune HD 21749b, both delivered by TESS. Follow-up…
SDSS-V Algorithms: Fast, Collision-Free Trajectory Planning for Heavily Overlapping Robotic Fiber Positioners
Conor Sayres, José R. Sánchez-Gallego, Michael R. Blanton +8
Robotic fiber positioner (RFP) arrays are becoming heavily adopted in wide field massively multiplexed spectroscopic survey instruments. RFP arrays decrease nightly operational ove…
The Astrophysical Distance Scale III: Distance to the Local Group Galaxy WLM using Multi-Wavelength Observations of the Tip of the Red Giant Branch, Cepheids, and JAGB Stars
Abigail J. Lee, Wendy L. Freedman, Barry F. Madore +3
The local determination of the Hubble Constant sits at a crossroad. Current estimates of the local expansion rate of the Universe differ by about 1.7-sigma, derived from the Cephei…
Cluster analysis of presolar silicon carbide grains: evaluation of their classification and astrophysical implications
Asmaa Boujibar, Samantha Howell, Shuang Zhang +9
Cluster analysis of presolar silicon carbide grains based on literature data for 12C/13C, 14N/15N, δ30Si/28Si, and δ29Si/28Si including or not inferred initial 26Al/27Al data, reve…
On the Use of Field RR Lyrae as Galactic Probes. II. A new S calibration to estimate their metallicity
J. Crestani, M. Fabrizio, V. F. Braga +33
We performed the largest and most homogeneous spectroscopic survey of field RR Lyraes (RRLs). We secured 6,300 high resolution (HR, R35,000) spectra for 143 RRLs (11…
Presolar Stardust in Highly Pristine CM Chondrites Asuka 12169 and Asuka 12236
Larry R. Nittler, Conel M. O'D. Alexander, Andrea Patzer +1
We report a NanoSIMS search for presolar grains in the CM chondrites Asuka (A) 12169 and A12236. We found 90 presolar O-rich grains and 25 SiC grains in A12169, giving matrix-norma…
A Swift Fix for Nuclear Outbursts
Jason T. Hinkle, Thomas W. -S. Holoien, Benjamin. J. Shappee +1
In November 2020, the Swift team announced an update to the UltraViolet and Optical Telescope calibration to correct for the loss of sensitivity over time. This correction affects…
Strong Near-Infrared Carbon Absorption in the Transitional Type Ia SN 2015bp
S. D. Wyatt, D. J. Sand, E. Y. Hsiao +20
Unburned carbon is potentially a powerful probe of Type Ia supernova (SN) explosion mechanisms. We present comprehensive optical and near-infrared (NIR) data on the "transitional"…
Fast Optical Transients from Stellar-Mass Black Hole Tidal Disruption Events in Young Star Clusters
Kyle Kremer, Wenbin Lu, Anthony L. Piro +3
Observational evidence suggests that the majority of stars may have been born in stellar clusters or associations. Within these dense environments, dynamical interactions lead to h…
An extended halo around an ancient dwarf galaxy
Anirudh Chiti, Anna Frebel, Joshua D. Simon +7
The Milky Way is surrounded by dozens of ultra-faint (< solar luminosities) dwarf satellite galaxies. They are the surviving remnants of the earliest galaxies, as confirmed…
Distances to PHANGS Galaxies: New Tip of the Red Giant Branch Measurements and Adopted Distances
