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 […]

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 […]

Dominating Set Reconfiguration with Answer Set Programming

Posted by dbos Tokyo

Kavli Affiliate: Naoyuki Tamura | First 5 Authors: Masato Kato, Torsten Schaub, Takehide Soh, Naoyuki Tamura, Mutsunori Banbara | Summary: The dominating set reconfiguration problem is defined as determining, for a given dominating set problem and two among its feasible solutions, whether one is reachable from the other via a sequence of feasible solutions subject […]

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 […]

Quantifying Bursty Star Formation in Dwarf Galaxies

Posted by dbos Chicago

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Yuan-Sen Ting, Alexander P. Ji, , , | Summary: Dwarf galaxy star formation histories are theoretically expected to be bursty, potentially leaving distinct imprints on their chemical evolution. We propose that episodic starbursts with quiescent periods longer than $sim$100 Myr should lead to discontinuous tracks in […]
