The Properties of Little Red Dot Galaxies in the ASTRID Simulation
Patrick LaChance, Rupert A. C. Croft, Tiziana Di Matteo +5
We present simulated counterparts of the ``Little Red Dot'' (LRD) galaxies observed with JWST, using the large cosmological hydrodynamic simulation, ASTRID. We create mock observat…
Large-scale surveys of the quasar proximity effect
Rupert A. C. Croft, Patrick Shaw, Ann-Marsha Alexis +6
The UV radiation from high redshift quasars causes a local deficit in the neutral hydrogen absorption (Lyman-alpha forest) in their spectra, known as the proximity effect. Measurem…
Large-scale dual AGN in large-scale cosmological hydrodynamical simulations
Clara Puerto-Sánchez, Melanie Habouzit, Marta Volonteri +10
Detecting dual active galactic nuclei (DAGN) in observations and understanding theoretically which massive black holes (MBHs) compose them and in which galactic and large-scale env…
PRIYA: A New Suite of Lyman-alpha Forest Simulations for Cosmology
Simeon Bird, Martin Fernandez, Ming-Feng Ho +6
We present the PRIYA suite of cosmological simulations, based on the code and hydrodynamic model of the ASTRID simulation, and designed for cosmological analyses of the Lyman- f…
The CAMELS project: Expanding the galaxy formation model space with new ASTRID and 28-parameter TNG and SIMBA suites
Yueying Ni, Shy Genel, Daniel Anglés-Alcázar +12
We present CAMELS-ASTRID, the third suite of hydrodynamical simulations in the Cosmology and Astrophysics with MachinE Learning (CAMELS) project, along with new simulation sets tha…
A new approach to constrain the Hubble expansion rate at high redshifts by gravitational waves
Mohammadtaher Safarzadeh, Karan Jani, Nianyi Chen +2
Detection of massive binary black hole (BBH) mergers at high redshifts is a target for LISA space mission. While the individual masses of a BBH merger are redshifted, the mass rati…
A close quasar pair in a disk-disk galaxy merger at z = 2.17
Yu-Ching Chen, Xin Liu, Adi Foord +7
Galaxy mergers produce pairs of supermassive black holes (SMBHs), which may be witnessed as dual quasars if both SMBHs are rapidly accreting. The kiloparsec (kpc)-scale separation…
Patchy Kinetic Sunyaev-Zel'dovich Effect with Controlled Reionization History and Morphology
Nianyi Chen, Hy Trac, Suvodip Mukherjee +1
Using the novel semi-numerical code for reionization AMBER, we model the patchy kinetic Sunyaev-Zel'dovich (kSZ) effect by directly specifying the reionization history with the red…
AMBER: A Semi-numerical Abundance Matching Box for the Epoch of Reionization
Hy Trac, Nianyi Chen, Ian Holst +2
The Abundance Matching Box for the Epoch of Reionization (AMBER) is a semi-numerical code for modeling the cosmic dawn. The new algorithm is not based on the excursion set formalis…
Data Compression and Covariance Matrix Inspection: Cosmic Shear
Tassia Ferreira, Tianqing Zhang, Nianyi Chen +1
Covariance matrices are among the most difficult pieces of end-to-end cosmological analyses. In principle, for two-point functions, each component involves a four-point function, a…
SCORCH. III. Analytical Models of Reionization with Varying Clumping Factors
Nianyi Chen, Aristide Doussot, Hy Trac +1
In the Simulations and Constructions of the Reionization of Cosmic Hydrogen (SCORCH) project, we compare analytical models of the hydrogen ionization fraction with radiation-hydrod…
