LYRA: The formation and growth of nuclear star clusters in dwarf galaxies
Joaquin Sureda, Azadeh Fattahi, Sownak Bose +5
Nuclear star clusters (NSCs) are dense massive star clusters ubiquitous in galactic centres across various mass regimes, present in up to per cent of dwarf galaxies with $…
Extreme Enrichment at Cosmic Dawn: Three FeII-Strong Quasars at z > 6 from the JWST Aether survey
Anniek J. Gloudemans, Emanuele Paolo Farina, Roberto Decarli +22
We present three outliers on the quasar main sequence at z>6, as revealed by JWST/NIRSpec IFU observations from the Aether survey, a program targeting ~200 quasars at cosmic dawn.…
To be lensed or not to be lensed: on the nature of the alleged high-z lensed quasars J0109-5424 and P170+20
Aurora Mata-Sanchez, Emanuele P. Farina, Anniek J. Gloudemans +17
We present a detailed multi-wavelength analysis of two gravitationally lensed z>6 quasar candidates: J0109-5424 and P170+20. Using JWST/NIRSpec near-infrared data from the Aether s…
LYRA ultra-faints: The emergence of faint dwarf galaxies in the presence of an early Lyman-Werner background
Shaun T. Brown, Azadeh Fattahi, Thales A. Gutcke +6
We present a suite of zoom-in cosmological hydrodynamical simulations of dwarf galaxies using the LYRA galaxy formation model with an extremely high mass resolution of $4\, \mathrm…
Co-evolution of baryons and dark matter halos of LYRA dwarf galaxies
Joaquin Sureda, Shaun T. Brown, Azadeh Fattahi +4
We use the extremely high-resolution () LYRA cosmological galaxy formation simulations of six dwarf galaxies with at…
Self-interacting dark matter in the center of a Local Group dwarf galaxy and its satellites
Thales A. Gutcke, Giulia Despali, Stephanie O'Neil +3
We present a detailed comparison of a Local Group dwarf galaxy analogue evolved in two cosmological models: the standard CDM and a self-interacting dark matter (SIDM) model with…
