Emulation of the Halo Mass Function with Neural Networks

Olive Ross, Nicholas Battaglia

The abundance of galaxy clusters as a function of mass --- the halo mass function (HMF) --- depends strongly on cosmological parameters. Large-scale simulations are computationally…

Probing Baryons with the Kinematic Sunyae Zel'dovich Effect and Machine Learning Derived Peculiar Velocities using DESI DR2 and ACT DR6

Yulin Gong, Rachel Bean, Patricio A. Gallardo +54

We present novel empirical constraints on average optical depths and gas density profiles from combining kinematic Sunyaev Zel'dovich effect (kSZ) measurements and nonlinear peculi…

Optical Depths from the Thermal Sunyaev-Zel'dovich Effect with ACT DR6 and DESI DR1 Spectroscopic Galaxies and Optically-Selected Clusters

J. E. Moore, C. Popik, Y. Gong +66

We present stacked thermal Sunyaev-Zel'dovich (tSZ) effect measurements for three samples of galaxy groups and clusters: those traced by the Dark Energy Spectroscopic Instrument Da…

Thermal Sunyaev-Zel'dovich Measurements of Locally Bright Galaxies with ACT DR6: Radio Source Contamination and Excess Compton-y Signal

Nicholas Battaglia, Jean-Baptiste Melin, J. Colin Hill +1

The Planck collaboration found a remarkable power-law relation between stellar mass and the thermal Sunyaev-Zeldovich (tSZ) signal for the Locally Bright Galaxy (LBG) sample, spann…

Weak-lensing mass calibration of \emph{Planck} Sunyaev--Zel'dovich clusters with HSC-SSP Year~3

Andrés Alejandro Plazas Malagón, Hironao Miyatake, Surhud More +3

We present a weak gravitational lensing mass calibration of 19 \textit{Planck} Sunyaev--Zel'dovich (SZ) selected galaxy clusters using shape measurements from the Hyper Suprime-Cam…

The Atacama Cosmology Telescope: A Test of the Gravitational Force Law on Cosmological Scales Using the Kinematic Sunyaev-Zeldovich Effect

Patricio A. Gallardo, Kris Pardo, Oliver H. E. Philcox +38

The mean pairwise velocity of massive halos reflects the gravitational force law on cosmic scales. We combine cosmic microwave background intensity maps from the Atacama Cosmology…
