The Search for Extraterrestrial Intelligence aims to find evidence of technosignatures, which can point toward the possible existence technologically advanced extraterrestrial life. Radio signals similar those engineered on Earth may be transmitted by other civilizations, motivating technosignature searches across entire radio spectrum. In this endeavor, low-frequency band has remained largely unexplored; with prior primarily above 1 GHz. survey at 110-190 MHz, observations 1,631,198 targets...
Modern radio interferometers such as the LOw Frequency ARray (LOFAR) are capable of producing data at hundreds gigabits to terabits per second. This high rate makes analysis cumbersome and computationally expensive. While performance computing facilities exist for large national international facilities, that may not be case instruments operated by a single institution or small consortium. Data rates next generation telescopes set eclipse those currently in operation, hence local processing...
Abstract We present high-spectral-resolution M -band spectra from iSHELL on NASA’s Infrared Telescope Facility along the line of sight to debris disk host star HD 32297. also a Gemini Planet Imager H polarimetric image 131488 disk. search for fundamental CO absorption lines in 32297, but do not detect any. place an upper limit column density ∼6 × 10 15 cm −2 . By combining limit, mass measured with Atacama Large Millimeter/submillimeter Array (ALMA), and geometrical properties disk, we...
The origin and evolution of CO gas in debris disks has been debated since its initial detection. could have a primordial origin, as remnant the protoplanetary disk or secondary exocometary origin. This paper investigates two disks, HD110058 HD131488, using HST observations CI CO, which play critical roles evolution. We fitted several electronic transitions rovibronic bands to derive column densities temperatures for each system, revealing high ($\sim$3-4 orders magnitude higher than $\beta$...

We present high-spectral resolution M-band spectra from iSHELL on NASA's Infrared Telescope Facility (IRTF) along the line of sight to debris disk host star HD 32297. also a Gemini Planet Imager (GPI) H-band polarimetric image 131488 disk. search for fundamental CO absorption lines in 32297 but do not detect any. place an upper limit column density $\sim$6$\times10^{15}$ cm$^{-2}$. By combining limit, mass measured with ALMA, and geometrical properties disk, we estimate scale height be...
