Diffuse Molecular Galactic Disk Survey
Is the Broad 18cm OH Emission ‘Disk’ in Concordance with Galactic Structure? We recently published the GBT discovery paper of a large amount of diffuse molecular gas, previously undetected by CO surveys (Busch et al. 2021). Present in sightlines towards the Outer Galaxy was an extremely faint (~2-4 mK/channel) signal of 1667 MHz OH emission…

GLUCOSE — The GBT L1544 Unbiased Complex Organics SurvEy
A high spectral and spacial sensitivity line survey will be carried out toward the prestellar core L1544 in the chemically rich Q-band (38-48.2 GHz), which has never before been attempted. Within the band are numerous energetically favorable complex organic molecule (COM) transitions compared to those in other surveys at higher frequency (i.e., the 3mm band),…

GDIGS-Low — GBT Diffuse Ionized Gas Survey at Low Frequencies
GDIGS-Low is a survey that will map radio recombination line (RRL) emission at 800 and 340 MHz over the inner Galactic plane (32° > ℓ > -5°). GDIGS-Low is a complement to the GDIGS survey. Through GDIGS-Low we will study the Warm Ionized Medium (WIM) and aim to answer (i) What are the physical properties…

Are astronomers seeing a signal from giant black holes?
World-wide radio telescope network strengthens evidence for signal that may hint at ultra-low frequency gravitational waves An international team of astronomers has discovered what could be the early sign of a background signal arising from supermassive black holes, observed through low-frequency gravitational waves. These scientists are comparing data collected from several instruments, including the National…
