Quasar Impostors: Two Extremely UV-Bright () Reionisation-Epoch Galaxies Powered by Very Massive Stars

Daming Yang, Joseph F. Hennawi, Sarah E. I. Bosman +20

The extreme bright end of the galaxy UV luminosity function during reionisation remains poorly constrained, particularly where the galaxy and quasar luminosity functions overlap an…

Euclid: Discovery of 31 new quasars at

D. Yang, J. F. Hennawi, F. Guarneri +211

We report the discovery of 31 new high- quasars in the redshift range . These quasars were selected from approximately 3000 deg of sky covered during the firs…

Possible chemical signatures of first-star enrichment in a very metal-poor galaxy overdensity near the end of reionization

Zihao Li, Koki Kakiichi, Lise Christensen +24

The first generation of stars, known as Population III (Pop III), formed from primordial gas consisting solely of hydrogen and helium and is believed to have emerged only a few hun…

ASPIRE: The Environments and Dark Matter Halos of Luminous Quasars in the Epoch of Reionization

Feige Wang, Jaclyn B. Champagne, Jiamu Huang +42

We present a systematic study of the environments of 25 luminous quasars at from the ASPIRE program. Using JWST/NIRCam WFSS data, we identified 487 galaxies at $5.3 \less…

The host halo masses of AGNs and quasars at with TNG-Cluster, FLAMINGO and other cosmological galaxy simulations

Akanksha Kapahtia, Annalisa Pillepich, Joey Braspenning +5

Most observations and clustering analyses suggest that quasars inhabit a narrow range of dark-matter halo masses ( M) across cosmic time (). Recen…

The Keck/DEIMOS Stellar Archive: I. Uniform Velocities and Metallicities for 78 Milky Way Dwarf Galaxies and Globular Clusters

Marla Geha, Debora Pelliccia, J. Xavier Prochaska +5

We present a homogeneous spectroscopic dataset of 22,339 stars in 78 Milky Way dwarf galaxy satellites and globular clusters. All data were taken with the Keck II telescope and Dee…
