21. AtLAST as a prebiotic molecule detector

Dr Izaskun Jiménez-Serra (Center of Astrobiology (CAB))

Invited talk

In the past decade, Astrochemistry has witnessed an impressive increase in the number of detections of new molecular species in space. The majority of these detections are related to complex organic molecules (or COMs), defined as carbon-based compounds with more than five atoms in their molecular structure. Interestingly, some of these complex organics are of prebiotic interest, and hence,...

11. Unveiling the hidden architecture from AGB winds to Planetary Nebulae

Teresa Huertas Roldán (Instituto de Astrofísica de Canarias)

Contributed talk

This project exploits the sensitivity, angular resolution, and high-frequency coverage of AtLAST to investigate key processes in late stellar evolution. We target compact and extended sources linked to post-AGB stars and planetary nebulae. For compact objects, we focus on pre-planetary nebulae with rotating disks, divided into high- and low-momentum subclasses. Using mm-wavelength radio...

14. Unveiling the aromatic Galaxy with AtLAST

Dr Víctor M. Rivilla (Centro de Astrobiología (CAB), CSIC-INTA)

Contributed talk

In recent years, two ultra-long (>1000 hr) single-dish spectral surveys toward the cold and quiescent molecular cloud TMC-1 have identified over 20 molecules containing five- and six-membered carbon rings, from benzonitrile (1 ring) to cyanocoronene (7 rings). These species are the simplest representatives of polycyclic aromatic hydrocarbons (PAHs), believed to account for a significant...

4. Simulating mapping observations with AtLAST

Thomas Morris (Yale University)

Contributed talk

The maria simulator ([https://thomaswmorris.com/maria/][1]) is a python-based, comprehensive tool for simulating mapping observations with direct-detection instruments such as kinetic inductance detectors or bolometers. Ongoing work includes expanding its functionality to include spectroscopy and the use of GPU-accelerated code. I will provide a quick demonstration of its capabilities...
