From Halos to Galaxies. VI. Improved halo mass estimation for SDSS groups and measurement of the halo mass function

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Dingyi Zhao, Yingjie Peng, Yipeng Jing, Xiaohu Yang, Luis C. Ho | Summary: In $Lambda$CDM cosmology, galaxies form and evolve in their host dark matter (DM) halos. Halo mass is crucial for understanding the halo-galaxy connection. The abundance matching (AM) technique has been widely used to derive […]

Evolving Dark Energy or Supernovae Systematics?

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 […]

JWST/NIRSpec WIDE survey: a z=4.6 low-mass star-forming galaxy hosting a jet-driven shock with low ionisation and solar metallicity

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Francesco D’Eugenio, Roberto Maiolino, Vijay H. Mahatma, Giovanni Mazzolari, Stefano Carniani | Summary: We present NIRSpec/MSA observations from the JWST large-area survey WIDE, targeting the rest-frame UV-optical spectrum of Ulema, a radio-AGN host at redshift z=4.6348. The low-resolution prism spectrum displays high equivalent width nebular emission, with […]

JADES Ultra-red Flattened Objects: Morphologies and Spatial Gradients in Color and Stellar Populations

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Justus L. Gibson, Erica Nelson, Christina C. Williams, Sedona H. Price, Katherine E. Whitaker | Summary: One of the more surprising findings after the first year of JWST observations is the large number of spatially extended galaxies (ultra-red flattened objects, or UFOs) among the optically-faint galaxy population […]

GA-NIFS: Multi-phase outflows in a star-forming galaxy at $z sim 5.5$

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Eleonora Parlanti, Stefano Carniani, Giacomo Venturi, Rodrigo Herrera-Camus, Santiago Arribas | Summary: Galactic outflows driven by star formation or active galactic nuclei are typically formed by multi-phase gas whose temperature spans over 4 orders of magnitude. Probing the different outflow components requires multi-wavelength observations and long exposure […]
