Theoretical emission lines and metallicity calibrations of H II regions in ASTRID simulation

Yao Yao, Kathryn Grasha, Stuart Wyithe +5

We present a theoretical framework to derive redshift-dependent metallicity calibrations for galaxies at =2-7. The ionization parameter () and gas pressure () in our appro…

Cosmic Pairs: A DESI Census of Dual and Offset AGN as Precursors to Massive Black Hole Binaries

Ekaterine Dadiani, Antonella Palmese, Yihao Zhou +52

We present a systematic census of dual and offset active galactic nuclei (AGN) using spectroscopic data from the first data release (DR1) of the Dark Energy Spectroscopic Instrumen…

Supermassive Black Hole Assembly from Heavy Seeds with Dynamical Friction in the BRAHMA Simulations: Implications for JWST, LISA, and the Local Universe

Aklant K. Bhowmick, Laura Blecha, Paul Torrey +8

The JWST discoveries of supermassive black holes (BHs) at may provide key insights into their seeding origins. Using new BRAHMA cosmological sim…

Matter Clustering in Astrid: Reduced Baryonic Suppression from Realistic Black Hole Dynamics

Yanhui Yang, Simeon Bird, Yihao Zhou +4

Baryonic feedback from active galactic nuclei (AGN) is often invoked as a major source of suppression in the matter power spectrum, with implications for precision cosmology and th…

The ASTRID Simulation at z=0: From Massive Black Holes to Large-scale Structure

Yihao Zhou, Tiziana Di Matteo, Simeon Bird +7

We present the results for the cosmological simulation ASTRID. Hosting 0.33 trillion particles in a box of per side, ASTRID is one o…
