Unraveling Chemical Enrichment in Extreme Emission-Line Galaxies: A Multi-Element Bayesian View of Bursty Star Formation and Galaxy Evolution in DESI
Razieh Emami, James A. A. Trussler, Tiger Yu-Yang Hsiao +11
Extreme emission-line galaxies (EELGs) probe chemical enrichment in low-mass, bursty systems where star formation, feedback, and gas accretion are poorly constrained. Using DESI DR…
Modeling X-ray photon pile-up with a normalizing flow
Ole König, Daniela Huppenkothen, Douglas Finkbeiner +5
The dynamic range of imaging detectors flown on-board X-ray observatories often only covers a limited flux range of extrasolar X-ray sources. The analysis of bright X-ray sources i…
Galaxy formation with wave/fuzzy dark matter: The core-halo structure and the solitonic imprint
Alvaro Pozo, Razieh Emami, Philip Mocz +9
Dark matter-dominated cores have long been claimed for the well-studied local group dwarf galaxies. More recently, extended stellar halos have been uncovered around several of thes…
Unravelling the role of merger histories in the population of In situ stars: linking IllustrisTNG cosmological simulation to H3 survey
Razieh Emami, Lars Hernquist, Randall Smith +16
We undertake a comprehensive investigation into the distribution of in~situ stars within Milky Way-like galaxies, leveraging TNG50 simulations and comparing their predictions with…
Novel Polarimetric Analysis of Near Horizon Flaring Episodes in M87* in Millimeter Wavelength
Razieh Emami, Matthew Liska, Koushik Chatterjee +15
Recent multi-wavelength observations of M87* \citep{2024A&A...692A.140A} revealed a high-energy -ray flare without a corresponding millimeter counterpart. We present a theoreti…
