DESCRIPTION:Speakers: Claudia Cicone (Institute of Theoretical Astrophysic
 s University of Oslo)\n\nAstronomical observations at (sub-)millimeter ((s
 ub-)mm) wavelengths are uniquely suited for studying regions of the Univer
 se that are too cold\, too dusty\, too distant\, or too hot and tenuous to
  be probed in the visible and at other wavelengths. Current (sub-)mm teles
 copes have achieved major breakthroughs\, beyond what is possible with opt
 ical and infrared observations. However\, many emerging science goals now 
 exceed the capabilities of existing telescopes. Achieving the next transfo
 rmational leap in discovery requires a new\, large-aperture (50-meter)\, m
 ulti-purpose single-dish telescope with a wide field of view (FoV\, >=1 de
 g) and a fast mapping speed across the full (sub-)mm band (30-950 GHz). Th
 ese requirements cannot be met through upgrades of existing facilities\, b
 ut demand a fundamentally new approach to telescope and instrument design.
 In parallel\, climate change and fuel price volatility are challenging man
 y fields\, including astronomy\, to become more sustainable and responsibl
 y use energy resources. Because they require clear skies\, dry atmospheric
  conditions\, and a pristine radio environment\, major astronomical observ
 atories are often located in remote areas\, sometimes near communities wit
 h limited access to reliable power. Telescope operations are power intensi
 ve\, and\, particularly in the (sub-)mm/radio bands\, they may continue up
  to 24 hours per day requiring a continuous year-round power supply. Histo
 rically\, sustainability has not been a primary driver in observatory desi
 gn and operations\, leading to continuous dependence on fossil fuels. Acti
 ve research in the field of renewable energy\, tailored to the needs of as
 tronomical facilities\, is therefore a necessary first step towards a mean
 ingful transition.The dual ambition to pursue transformational science in 
 the (sub-)mm and make astronomy sustainable has motivated the Atacama Larg
 e Aperture Submillimeter Telescope (AtLAST (https://www.atlast.uio.no). In
  this seminar\, I will summarise the current status of AtLAST development\
 , showing the results of the EU-funded Design Study (AtLAST\, 2021-2024 ht
 tps://cordis.europa.eu/project/id/951815)\, and preliminary results from t
 he ongoing EU-funded design consolidation project (AtLAST2\, 2025-2028\, h
 ttps://cordis.europa.eu/project/id/101188037).\n\nhttps://agenda.infn.it/e
