Chromaticity-Optimized Antenna Design and Bayesian Foreground Validation for the CANTAR Global 21 cm Experiment
Michelle Mora, German Chaparro, Juan D. Guerrero +6
Detecting the global 21 cm signal from the epoch of reionization remains a major observational challenge due to bright foregrounds and instrumental systematics. As part of the Colo…
Blade Antenna-SDR System Prototype for the CANTAR Global 21-cm Experiment: Simulations, Measurements, and In-Situ Results
F. P. Mosquera, J. Rodriguez-Ferreira, E. Acevedo +3
We present the design and initial testing of a low-frequency radio telescope prototype developed for the CANTAR (Colombian Antarctic Telescope for 21-cm Absorption during Reionizat…
XUE. JWST spectroscopy of externally irradiated disks around young intermediate-mass stars
MarÃa Claudia RamÃrez-Tannus, Arjan Bik, Konstantin V. Getman +17
Most young stars and therefore planetary systems form in high-mass star forming regions and are exposed to ultraviolet radiation, affecting the protoplanetary disk. These regions a…
XUE 10. The CO2-rich terrestrial planet-forming region of an externally irradiated Herbig disk
Jenny Frediani, Arjan Bik, MarÃa Claudia RamÃrez-Tannus +18
We investigate the James Webb Space Telescope (JWST) MIRI MRS gas molecular content of an externally irradiated Herbig disk, the F-type XUE 10 source, in the context of the eXtreme…
Pattern Finding in mm-Wave Spectra of Massive Young Stellar Objects
Yenifer Angarita, Germán Chaparro, Stuart L. Lumsden +4
Massive stars play a pivotal role in shaping their galactic surroundings due to their high luminosity and intense ionizing radiation. However, the precise mechanisms governing the…
