An Attenuation Bump at z=9.3: Probing Dust Diversity at Cosmic Dawn
Giulia Rodighiero, Santiago Álvarez-Córdoba, Michele Catone +46
We report the identification of a UV attenuation bump in the Black Pearl, a galaxy at a spectroscopic redshift of 9.3335 observed with JWST/NIRSpec as part of the ZENITH and EMBER…
The impact of stellar binaries and star cluster dynamics on pair-instability supernovae
Francesco Gabrielli, Cristiano Ugolini, Lavinia Paiella +12
Pair-instability supernovae (PISNe) are among the most luminous transients in the Universe. However, they have never been confidently observed. Solving this puzzle would have key i…
A Relativistic Scalar Model for Fractional Interaction between Dark Matter and Gravity
Francesco Benetti, Andrea Lapi, Giovanni Gandolfi +1
In a series of recent papers we put forward a ``fractional gravity'' framework striking an intermediate course between a modified gravity theory and an exotic dark matter (DM) scen…
Constraining the Initial Mass function in the Epoch of Reionization from Astrophysical and Cosmological data
A. Lapi, G. Gandolfi, L. Boco +6
[abridged] We aim to constrain the stellar initial mass function (IMF) during the epoch of reionization. To this purpose, we build up a semi-empirical model for the reionization hi…
Observing Dusty Star-Forming Galaxies at the Cosmic Noon through Gravitational Lensing: Perspectives from New Generation Telescopes
Marika Giulietti, Giovanni Gandolfi, Marcella Massardi +2
Gravitational lensing, a compelling physical phenomenon, offers a unique avenue to investigate the morphology and physical properties of distant and faint celestial objects. This p…
Dark Matter in Fractional Gravity III: Dwarf Galaxies Kinematics
F. Benetti, A. Lapi, G. Gandolfi +4
Recently we put forward a framework where the dark matter (DM) component within virialized halos is subject to a non-local interaction originated by fractional gravity (FG) effects…
Dark Matter in Fractional Gravity II: Tests in Galaxy Clusters
Francesco Benetti, Andrea Lapi, Giovanni Gandolfi +2
[abridged] Recently, in Benetti et al. (Astrophys. J. 2023, 949, 65), we suggested that the dark matter (DM) component in galaxies may originate fractional gravity. In such a frame…
Looking for Traces of Non-minimally Coupled Dark Matter in the X-COP Galaxy Clusters Sample
Giovanni Gandolfi, Balakrishna Sandeep Haridasu, Stefano Liberati +1
We look for possible evidence of a non-minimal coupling (NMC) between dark matter (DM) and gravity using data from the X-COP compilation of galaxy clusters. We consider a theoretic…
The Way of Water: ALMA resolves H2O emission lines in a strongly lensed dusty star-forming galaxy at z 3.1
F. Perrotta, M. Giulietti, M. Massardi +10
We report ALMA high-resolution observations of water emission lines ), , , in the strong…
Dark Matter in Fractional Gravity I: Astrophysical Tests on Galactic Scales
Francesco Benetti, Andrea Lapi, Giovanni Gandolfi +2
[abridged] We explore the possibility that the dark matter (DM) component in galaxies may originate fractional gravity. In such a framework, the standard law of inertia continues t…
Delving deep: a population of extremely dusty dwarfs observed by JWST
L. Bisigello, G. Gandolfi, A. Grazian +21
We take advantage of the NIRCam photometric observations available as part of the Cosmic Evolution Early Release Science survey (CEERS) to identify and analyse very red sources in…
Astroparticle Constraints from the Cosmic Star Formation Rate Density at High Redshift: Current Status and Forecasts for JWST
Giovanni Gandolfi, Andrea Lapi, Tommaso Ronconi +1
We exploit the recent determination of cosmic star formation rate (SFR) density at redshifts to derive astroparticle constraints on three common dark matter scenarios…
Empirical Evidence of Non-Minimally Coupled Dark Matter in the Dynamics of Local Spiral Galaxies?
Giovanni Gandolfi, Andrea Lapi, Stefano Liberati
We look for empirical evidence of a non-minimal coupling (NMC) between dark matter (DM) and gravity in the dynamics of local spiral galaxies. In particular, we consider a theoretic…
Self-gravitating Equilibria of Non-minimally Coupled Dark Matter Halos
Giovanni Gandolfi, Andrea Lapi, Stefano Liberati
We investigate self-gravitating equilibria of halos constituted by dark matter (DM) non-minimally coupled to gravity. In particular, we consider a theoretically motivated non-minim…
