Going deeper into the dark with COSMOS-Web: JWST unveils the total contribution of Radio-Selected NIRfaint galaxies to the cosmic Star Formation Rate Density
Fabrizio Gentile, Margherita Talia, Andrea Enia +34
We present the first follow-up with JWST of radio-selected NIRfaint galaxies as part of the COSMOS-Web survey. By selecting galaxies detected at radio frequencies ($S_{\rm 3 GHz}>1…
A FLASH on Blazars: Capturing the Radio Realm of 4FGL Blazars with SKAO Pathfinders
Meriem Behiri, Elizabeth Mahony, Elaine Sadler +6
This work investigates the multi-wavelength properties of 165 4FGL blazars from the Fermi-LAT fourth source catalogue, looking for with counterparts in the Australian SKA Pathfinde…
Radio selection of heavily obscured AGN in the J1030 field: unraveling a missing Compton-thick population
Giovanni Mazzolari, Roberto Gilli, Marco Mignoli +21
We tested the effectiveness of radio selection to discover heavily obscured AGNs, particularly at high-z, and we measured their abundance for the first time from a radio perspectiv…
The role of young and evolved stars in the heating of dust in local galaxies
Vidhi Tailor, Viviana Casasola, Francesca Pozzi +9
Context. Dust is a fundamental component of the interstellar medium (ISM) and plays a critical role in galaxy evolution. Dust grains influence the ISM by cooling the gas, altering…
ACOSMOS: Measuring the cosmic dust-attenuated star formation rate density at
Benjamin Magnelli, Sylvia Adscheid, Tsan-Ming Wang +14
[Abridged] In recent years, conflicting results have provided an uncertain view of the dust-attenuated properties of star-forming galaxies (SFGs). To solve this, we used the…
ACOSMOS and AGOODSS: Continuum Source Catalogues and Multi-band Number Counts
Sylvia Adscheid, Benjamin Magnelli, Daizhong Liu +7
Galaxy submillimetre number counts are a fundamental measurement in our understanding of galaxy evolution models. Most early measurements are obtained via single-dish telescopes wi…
Compton-thick AGN in the NuSTAR Era X: Analysing seven local CT-AGN candidates
Dhrubojyoti Sengupta, Stefano Marchesi, Cristian Vignali +14
We present the broad-band X-ray spectral analysis (0.6-50 keV) of seven Compton-Thick active galactic nuclei (CT-AGN; line-of-sight, l.o.s., column density cm) ca…
Strong environmental AGN enhancement among DSFGs in z > 2 protoclusters
Monica Natalia Isla Llave, Fabio Vito, Alberto Traina +17
Galaxy protoclusters (PCs) at z > 2 are dense regions in which cold gas availability and elevated galaxy interaction rates trigger intense, often dust-obscured, star formation. The…
2FHLJ1745.1-3035: A Newly Discovered, Powerful Pulsar Wind Nebula Candidate
Stefano Marchesi, Jordan Eagle, Marco Ajello +8
We present a multi-epoch, multi-observatory X-ray analysis for 2FHL J1745.1-3035, a newly discovered very high energy Galactic source detected by the Fermi Large Area Telescope (LA…
Compton-Thick AGN in the NuSTAR era VII. A joint NuSTAR, Chandra and XMM-Newton analysis of two nearby, heavily obscured sources
Alberto Traina, Stefano Marchesi, Cristian Vignali +11
We present the joint Chandra, XMM-Newton and NuSTAR analysis of two nearby Seyfert galaxies, NGC 3081 and ESO 565-G019. These are the only two having Chandra data in a larger sampl…
MEOW: The increase in the obscured AGN fraction in mid-infrared from 0 < z < 6 with JWST MIRI
Teodora-Elena Bulichi, Gene C. K. Leung, Anna-Christina Eilers +16
Obscured active galactic nuclei (AGN) are often invoked to explain the rapid emergence of young quasars at high redshift and are crucial for building a complete census of AGN activ…
Narrow line AGN selection in CEERS: spectroscopic selection, physical properties, X-ray and radio analysis
Giovanni Mazzolari, Jan Scholtz, Roberto Maiolino +11
In this work, we spectroscopically select narrow-line AGNs (NLAGNs) among the ~300 publicly available medium-resolution spectra of the Cosmic Evolution Early Release Science Survey…
Dark progenitors and massive descendants: A first ALMA perspective on Radio-Selected NIRdark galaxies in the COSMOS field
Fabrizio Gentile, Margherita Talia, Emanuele Daddi +19
We present the first spectroscopic ALMA follow-up for a pilot sample of nine Radio-Selected NIRdark galaxies in the COSMOS field. These sources were initially selected as radio-det…
Need for PRIMA to understand the nature and ISM physical conditions of HST-dark galaxies
Carlotta Gruppioni, Lee Armus, Matthieu Bethermin +10
One of the main open issues in galaxy formation and evolution is the early assembly of the most massive galaxies and their contribution to the stellar mass and star formation rate…

Stefano Marchesi, Xiurui Zhao, Núria Torres-Albà +18
We present the multi-epoch monitoring with NuSTAR and XMM-Newton of NGC 1358, a nearby Seyfert 2 galaxy whose properties made it a promising candidate X-ray changing look AGN, i.e.…
