ALMA2040: The High-Redshift Circumgalactic Medium. Imaging the fueling and feedback of galaxies in the early universe
Kirsty M. Butler, Justin Spilker, Seiji Fujimoto +23
Galaxies do not form in isolation, but rather as part of a wider interconnected web mediated at their interface by an extended gaseous atmosphere - the Circum-Galactic Medium (CGM)…
Probing cold gas and dust in quiescent galaxies across cosmic time
Anita Zanella, Sirio Belli, Belen Alcalde Pampliega +35
The discovery of massive quiescent galaxies at high redshift by JWST has revealed that star formation can cease rapidly in the early Universe, yet the physical mechanisms responsib…
Resolving the Assembly of Disk Galaxies from the Epoch of Reionisation to Cosmic Noon
Melanie Kaasinen, Mahsa Kohandel, Francesca Rizzo +45
Most of the mass and angular momentum of today's disk galaxies assembled at . Yet, it remains unclear how these galaxies acquired their gas, how their baryons and dark matter…
ALMA2040: Understanding the Early Assembly of Galaxies - The Formation of Star-Forming Clumps and their Role in Shaping Galaxy Evolution
Anita Zanella, Andreas L. Faisst, Rodrigo Herrera-Camus +25
Astrophysics seeks to explain how galaxies form and evolve through the interplay of stars, gas, and dust. Giant molecular clouds (GMCs), the main reservoirs and sites of star forma…
The Role of Environment in Shaping the Assembly Timelines of Massive Quiescent Galaxies at Cosmic Noon
Tianmu Gao, J. Trevor Mendel, Letizia Bugiani +10
JWST observations of massive quiescent galaxies (MQGs) at have revealed diverse star formation histories (SFHs). In this letter, we investigate whether these variations ar…
Toward the Italian Astronomical Community's Contribution to HWO: Science, Technology, and Instrument Concepts
A. Fontana, F. Annibali, N. Antonietti +101
This paper summarizes the interest of the Italian astronomical community in the possible participation in the development of the Habitable Worlds Observatory (HWO). It is largely b…
SN Helios: A Multiply Imaged Type II Supernova Opening Time-Delay Cosmography beyond redshift of 3
Seiji Fujimoto, Conor Larison, Justin D. R. Pierel +64
We report the discovery and spectroscopic confirmation of SN Helios, a strongly lensed, multiply imaged Type II supernova (SN) at behind the galaxy cluster RXC J0018.5+162…
A sub-100 pc view at z~5 of a Multiply-Imaged Massive Quiescent Galaxy
Richard Pan, Danilo Marchesini, Joseph F. V. Allingham +34
Recent James Webb Space Telescope spectroscopic surveys reveal an abundance of rapidly assembled early galaxies in the first billion years. Cosmological simulations struggle to rep…
Towards First Light for MICADO: Validation of the PSF-R service with real data
Matteo Simioni, Luca Cortese, Roland Wagner +12
MICADO, one of the ELT first-light instruments, will rely on point-spread-function reconstruction (PSF-R) to meet scientific requirements, especially for SCAO observations of targe…
The MICADO first light imager for the ELT: the PSF Reconstruction Software
Andrea Grazian, Fernando Pedichini, Matteo Simioni +14
The MICADO instrument for the ESO ELT will provide Adaptive Optics (AO) diffraction-limited NIR imaging and spectroscopy. A critical component of MICADO is the Point Spread Functio…
The MICADO first light imager for the ELT: Simulated Observations of Star Forming Clumps at Cosmic Noon
Matteo Simioni, Carmelo Arcidiacono, Andrea Grazian +18
Galaxies at redshift z2-6 exhibit prominent star-forming regions (clumps). Characterisation of these galactic structures requires both high sensitivity and spatial resolution…
Breathing Fire: Hot Dust in the Big Three Dragons at z = 7.15
Gitanjali Rajulal, Hiddo S. B. Algera, Yuma Sugahara +25
We present new Atacama Large Millimeter/submillimeter Array (ALMA) Band 9 () and 4 () observations towards th…
No evolution in the number density of little red dots from cosmic dawn to cosmic noon
Federica Loiacono, Roberto Gilli, Marco Mignoli +24
We present our search for little red dots (LRDs) in the "J1030 field", a region of the sky around the quasar SDSS J1030+0524, observed by the JWST EIGER program. Over 1…
The MICADO first light imager for the ELT: the PSF Reconstruction Software
Andrea Grazian, Elisa Portaluri, Matteo Simioni +10
MICADO is the first-light camera of the ESO ELT, allowing NIR imaging and long-slit spectroscopy assisted by adaptive optics. MICADO is now entering its construction phase, and the…
The MICADO first light imager for the ELT: off-axis performance of PSF reconstruction
Matteo Simioni, Daniel Jodlbauer, Carmelo Arcidiacono +14
The highest scientific return, for adaptive optics (AO) observations, is achieved with a reliable reconstruction of the PSF. This is especially true for MICADO@ELT. In this present…
Towards the MICADO@ELT PSF-R with simulated and real data
Matteo Simioni, Carmelo Arcidiacono, Andrea Grazian +5
Observations close to the diffraction limit, with high Strehl ratios from Adaptive Optics (AO)-assisted instruments mounted on ground-based telescopes are a reality and will become…
Design and evaluation of a multi-sensory representation of scientific data
Stefania Varano, Anita Zanella
Modern sciences and astrophysics in particular study objects and phenomena not visible in physical terms, that is they cannot be investigated with the eyes or analogous optical sys…
Status of the PSF Reconstruction Work Package for MICADO ELT
