The atmosphere of K2-18 b: The role of hazes, clouds and photoelectrons
P. Lavvas, R. Liu, G. Tinetti +3
The atmospheric characterisation of temperate exoplanets is becoming accessible with JWST, providing a critical connection between Solar System planets and the more commonly observ…
Detection of the Pairwise Kinematic Sunyaev-Zel'dovich Effect and Pairwise Velocity with DESI DR1 Galaxies and ACT DR6 and Planck CMB Data
Yulin Gong, Patricio A. Gallardo, Rachel Bean +50
We present a 9.3-sigma detection of the pairwise kinematic Sunyaev-Zeldovich (kSZ) effect by combining a sample of 913,286 Luminous Red Galaxies (LRGs) from the Dark Energy Spectro…
Measurements of the Thermal Sunyaev-Zel'dovich Effect with ACT and DESI Luminous Red Galaxies
R. Henry Liu, Simone Ferraro, Emmanuel Schaan +54
Cosmic Microwave Background (CMB) photons scatter off the free-electron gas in galaxies and clusters, allowing us to use the CMB as a backlight to probe the gas in and around low-r…
Evidence for large baryonic feedback at low and intermediate redshifts from kinematic Sunyaev-Zel'dovich observations with ACT and DESI photometric galaxies
B. Hadzhiyska, S. Ferraro, B. Ried Guachalla +70
Recent advances in cosmological observations have provided an unprecedented opportunity to investigate the distribution of baryons relative to the underlying matter. In this work,…
Fast Baryonic Field Painting for Sunyaev-Zel'dovich Analyses: Transfer Function vs. Hybrid Effective Field Theory
R. Henry Liu, Boryana Hadzhiyska, Simone Ferraro +2
We present two approaches for "painting" baryonic properties relevant to the Sunyaev-Zel'dovich (SZ) effect - optical depth and Compton- - onto 3-dimensional -body simulation…
