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…
FAST-SBF: an automatic procedure for the measurement of Surface Brightness Fluctuations for large sky surveys
Gabriele Riccio, Michele Cantiello, Rebecca Habas +9
The Surface Brightness Fluctuation method is one of the most reliable and efficient ways of measuring distances to galaxies within 100 Mpc. While recent implementations have increa…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Euclid: Early Release Observations of diffuse stellar structures and globular clusters as probes of the mass assembly of galaxies in the Dorado group
M. Urbano, P. -A. Duc, T. Saifollahi +160
Deep surveys reveal tidal debris and associated compact stellar systems. Euclid's unique combination of capabilities (spatial resolution, depth, and wide sky coverage) will make it…
Euclid: Quick Data Release (Q1) -- Photometric studies of known transients
C. Duffy, E. Cappellaro, M. T. Botticella +174
We report on serendipitous Euclid observations of previously known transients, using the Euclid Q1 data release. By cross-matching with the Transient Name Server (TNS) we identify…
VEGAS-SSS: An intra-group component in the globular cluster system of NGC 5018 group of galaxies using VST data
Pratik Lonare, Michele Cantiello, Marco Mirabile +7
Globular clusters (GCs) are fossil tracer of formation and evolution of galaxies and studying their properties provides crucial insights into past formation and interaction events.…
