47. OLIMPO: a Balloon-Borne SZE Imager to Probe ICM Dynamics and the WHIM

Jack Sayers (Caltech)

29/06/2023 09:00

I will present our concept and science projections for OLIMPO, a proposed Antarctic balloon-borne SZE imager to study gas dynamics associated with structure formation along with the properties of the WHIM thought to reside in large scale structure filaments and to comprise a significant fraction of the universal baryon budget. During a planned 25 day circum-polar flight in 2026 OLIMPO will...

57. The BLAST Observatory

Federico Nati (University of Milano-Bicocca)

29/06/2023 09:25

The Balloon-borne Large Aperture Submillimeter Telescope Observatory (BLAST Observatory) is a proposed NASA super-pressure balloon mission. BLAST Observatory will include a 1.8 m off-axis primary mirror and observe at 175, 250, and 350 microns simultaneously, with a total of 8274 polarization-sensitive microwave kinetic inductance detectors (MKIDs) cooled to 100 mK. The telescope will be...

41. Progress with the Atacama Large Aperture Submm Telescope

Tony Mroczkowski (European Southern Observatory (ESO))

29/06/2023 09:50

Here I will describe progress with AtLAST, a wide field of view (1-2 degree), 50-meter aperture single dish telescope that will be located at over 5000 meters above sea level, high in the Atacama Desert. AtLAST will accommodate a vast range of large (2 to 4.5 meter diameter) instruments operating from 30 GHz to 1 THz in a cabin that enables expedient switching between receivers. AtLAST will...

12. Large Millimeter Telescope Survey of the Galactic Central Molecular Zone

Q. Daniel Wang (University of Massachusetts)

29/06/2023 10:50

The central molecular zone (CMZ) of our Galaxy hosts an extreme interstellar environment analogous to that found in typical starburst galaxies in the distant Universe. In order to understand dust properties in such environments, we have conducted a survey of the CMZ with the AzTEC/Large Millimeter Telescope (LMT) in the 1.1 mm continuum. This survey has been analyzed together with...

38. Dust and gas of pre-stellar cores

Carsten Kramer (IRAM)

29/06/2023 11:10

Dust grain surface chemistry plays an important role in the formation and freeze-out of molecules that are key to the chemical network and govern the formation of cores from the diffuse interstellar medium. The evolution of dust properties such as grain sizes from the diffuse interstellar medium to dense cores is not well understood. We present IRAM-30m observations towards eight starless...

86. Dust grain evolution from star-forming filaments to T-Tauri stars: Results from NIKA2 observations of the Taurus B211/B213 filament in the GASTON large program

Quang Nguyen Luong (American University of Paris / CEA Paris-Saclay)

29/06/2023 11:35

Understanding the evolution of dust properties in molecular clouds is important for tracing the star formation process through submm observations. We aim at constraining the evolution of dust grains from star-forming filaments to prestellar and protostellar cores to T Tauri stars. Using the NIKA2 continuum camera on the IRAM 30~m telescope, we observed the Taurus B211/B213 filament in the...
