Euclid: Calibrating distances from surface brightness fluctuations with Early Release Observations of the Fornax cluster

R. Habas, M. Cantiello, G. Riccio +169

Surface brightness fluctuations (SBF), the pixel-to-pixel variations in flux that arise from the statistical distribution of stars in galaxy images, provide a powerful tool to meas…

The abundance and radial distribution of faint and ultra-faint dwarfs in galaxy clusters

Pradyumna Sadhu, Laura V. Sales, Julio F. Navarro +3

Cosmological simulations of galaxy clusters are unable to resolve dwarf galaxies due to limited numerical resolution which drives the artificial disruption of dark matter substruct…

Chemical radial gradients for the bulge-bar stellar populations from the APOGEE survey

J. V. Sales-Silva, K. Cunha, V. V. Smith +20

The Milky Way bulge-bar is composed of multiple populations. Using chemical and kinematical planes, we segregate six populations in a bulge-bar sample observed by the APOGEE survey…

PAC in DESI. II. Galaxy-halo connection into the frontier

Kun Xu, Carlos S. Frenk, Y. P. Jing +37

Understanding dwarf galaxy formation is crucial for testing dark matter models and reionization physics. However, constructing stellar-mass complete spectroscopic samples at low ma…

HE0144-4657: A Carbon-Enhanced Ultra Metal-Poor Star ([Fe/H] ~ -4.1) from the Helmi Stream Disrupted Dwarf Galaxy

Vinicius M. Placco, Guilherme Limberg, Catherine R. Kennedy +1

We present the discovery of HE0144-4657, an ultra metal-poor, CNO-enhanced star dynamically associated with the Helmi Stream disrupted dwarf-galaxy remnant. This star was first ide…
