Possible Evidence for the Presence of Volatiles on the Warm Super-Earth TOI-270 b
The search for atmospheres on rocky exoplanets is a crucial step in understanding the processes driving atmosphere formation, retention, and loss. Past studies have revealed the existence of planets interior to the radius valley with densities lower than would be expected for pure-rock compositions, indicative of the presence of large volatile inventories which could facilitate atmosphere retention. Here we present an analysis of the JWST NIRSpec/G395H transmission spectrum of the warm ($T_\mat…

Signal processing and data acquisition system for the BTO detectors onboard COSI
The energy range from a few hundred keV to a few MeV includes important probes such as nuclear gamma-rays and the 511 keV annihilation line. However, compared to X-rays and GeV/TeV gamma-rays, this range suffers from lower sensitivity by orders of magnitude. The upcoming NASA SMEX satellite mission Compton Spectrometer and Imager (COSI), scheduled for launch in 2027, is expected to break through this limitation with its Compton telescope utilizing a germanium semiconductor detector, covering th…
