Unveiling the Cosmic Chemistry: Revisiting the Mass-Metallicity Relation with JWST/NIRSpec at 4 < z < 10

Posted by dbos MIT

Kavli Affiliate: Eric Miller | First 5 Authors: Arnab Sarkar, Priyanka Chakraborty, Mark Vogelsberger, Michael McDonald, Paul Torrey | Summary: We present star formation rates (SFR), the mass-metallicity relation (MZR), and the SFR-dependent MZR across redshifts 4 to 10 using 81 star-forming galaxies observed by the JWST NIRSpec employing both low-resolution PRISM and medium-resolution gratings, […]

From Halos to Galaxies. X: Decoding Galaxy SEDs with Physical Priors and Accurate Star Formation History Reconstruction

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Zeyu Gao, Yingjie Peng, Kai Wang, Luis C. Ho, Alvio Renzini | Summary: The spectral energy distribution (SED) of galaxies is essential for deriving fundamental properties like stellar mass and star formation history (SFH). However, conventional methods, including both parametric and non-parametric approaches, often fail to […]

Testing galaxy formation models with the stellar mass-halo mass relations for star-forming and quiescent galaxies

Posted by dbos Peking

Kavli Affiliate: Yingjie Peng | First 5 Authors: Kai Wang, Yingjie Peng, , , | Summary: The tight relationship between the stellar mass and halo mass of galaxies is one of the most fundamental scaling relations in galaxy formation and evolution. It has become a critical constraint for galaxy formation models. Over the past decade, […]

Field-level Emulation of Cosmic Structure Formation with Cosmology and Redshift Dependence

Posted by dbos Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Drew Jamieson, Yin Li, Francisco Villaescusa-Navarro, Shirley Ho, David N. Spergel | Summary: We present a field-level emulator for large-scale structure, capturing the cosmology dependence and the time evolution of cosmic structure formation. The emulator maps linear displacement fields to their corresponding nonlinear displacements from N-body […]

Evolving Dark Energy or Supernovae Systematics?

Posted by dbos Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: George Efstathiou, , , , | Summary: Recent results from the Dark Energy Spectroscopic Instrument (DESI) collaboration have been interpreted as evidence for evolving dark energy. However, this interpretation is strongly dependent on which Type Ia supernova (SN) sample is combined with DESI measurements of baryon acoustic […]
