No Evidence for Nearby Circumstellar Material in the Type Ia Supernova 2025rbs
Aravind P. Ravi, Griffin Hosseinzadeh, Stefano Valenti +28
We present a high-resolution spectral time series of the Type Ia supernova (SN) 2025rbs discovered in the nearby galaxy NGC 7331. The Automated Planet Finder (APF) at Lick Observat…
On Cross-Correlating Line Intensity Maps from SPHEREx during Reionization
Abigail E. Ambrose, Eli Visbal, Matthew McQuinn
We have simulated Lyα, Hα, Hβ, [OII], and [OIII] intensity maps which are observable by SPHEREx during cosmic reionization. We simulate these intensity maps including all signif…
AGN Line-Intensity Mapping: A Probe of Faint Black Holes at Cosmic Noon
Eli Visbal, Greg L. Bryan
We propose line-intensity mapping (LIM) as a new probe of active galactic nuclei (AGN). By cross-correlating [Ne V] intensity maps with galaxy redshift surveys, we show that the cu…
Exploring the High-Redshift 21-cm Signal via Self-Consistent Simulations using Artificial Neural Network Emulation
Colton R. Feathers, Eli Visbal, Steven Murray +2
We present a novel, self-consistent, semi-numeric Cosmic Dawn (CD) simulation in which small-scale star formation (SF) is calibrated to the \emph{AEOS} and \emph{Renaissance} hydro…
Chemical Signatures of Population III Stars in Damped Lyman- Absorption Systems at
Eli Visbal, Greg L. Bryan, Zoltan Haiman
Recently, Sodini et al. (2024) presented a sample of OI damped Lyman- absorption system (DLA) analogs at that contain possible chemical signatures of Population III (P…
LAP1-B is the First Observed System Consistent with Theoretical Predictions for Population III Stars
Eli Visbal, Ryan Hazlett, Greg L. Bryan
Recently, Nakajima et al. (2025) presented James Webb Space Telescope observations of the Population III (Pop III) candidate LAP1-B, which is gravitationally lensed by gala…
