Primordial Magnetic Fields at Cosmic Dawn: 21-cm Forecasts with HERA and SKA
Keduse Worku, Hector Afonso G. Cruz, Marc Kamionkowski
Primordial magnetic fields (PMFs) can enhance the abundance of low-mass halos during Cosmic Dawn by sourcing additional small-scale matter fluctuations. This enhanced small-scale p…
High-Redshift Galaxy Candidates at z > 6 as Revealed by JWST Observations of MACS0647
Keduse Worku, Tiger Yu-Yang Hsiao, Dan Coe +9
We present a catalog of 57 high-redshift galaxy candidates, including 14 spectroscopic confirmations ( -- 9.25), 2 Little Red Dots (, 5.81), and 2 interlo…
Rapid Methods for Modeling Overdensities of Massive Neutrinos and Other Non-Cold Relics
Keduse Worku, Nashwan Sabti, Marc Kamionkowski
Recent work has highlighted the potentially detectable gravitational-lensing effect of neutrino halos on cosmic-microwave-background (CMB) fluctuations with upcoming instruments li…
Revisiting the Full Sets of Orbital Parameters for the XO-3 System: No evidence for Temporal Variation of the Spin-Orbit Angle
Keduse Worku, Songhu Wang, Jennifer Burt +14
We present 12 new transit light curves and 16 new out-of-transit radial velocity measurements for the XO-3 system. By modelling our newly collected measurements together with archi…
HD 202772A B: A Transiting Hot Jupiter Around A Bright, Mildly Evolved Star In A Visual Binary Discovered By Tess
Songhu Wang, Matias Jones, Avi Shporer +52
We report the first confirmation of a hot Jupiter discovered by the Transiting Exoplanet Survey Satellite (TESS) mission: HD 202772A b. The transit signal was detected in the data…
