Introduction to the Special Issue on Sounding Rockets and Instrumentation
Steven Christe, Ben Zeiger, Rob Pfaff +1
Rocket technology, originally developed for military applications, has provided a low-cost observing platform to carry critical and rapid-response scientific investigations for ove…
Design and Performance of the X-ray polarimeter X-Calibur
Matthias Beilicke, F. Kislat, A. Zajczyk +13
X-ray polarimetry promises to give qualitatively new information about high-energy astrophysical sources, such as binary black hole systems, micro-quasars, active galactic nuclei,…
Formaldehyde Silhouettes Against the Cosmic Microwave Background: A Mass-Limited, Distance-Independent, Extinction-Free Tracer of Star Formation Across the Epoch of Galaxy Evolution
Jeremy Darling, Benjamin Zeiger
We examine the absorption of cosmic microwave background (CMB) photons by formaldehyde (H2CO) over cosmic time. The K-doublet rotational transitions of H2CO become "refrigerated" -…
Galactic H2CO Densitometry I: Pilot survey of Ultracompact HII regions and methodology
Adam Ginsburg, Jeremy Darling, Cara Battersby +2
We present a pilot survey of 21 lines of sight towards UCHII regions in the H2CO 1-1 (6cm) and 2-2 (2cm) transitions, using the H2CO centimeter lines as a molecular gas densitomete…
Formaldehyde Anti-Inversion at z=0.68 in the Gravitational Lens B0218+357
Benjamin Zeiger, Jeremy Darling
We report new observations of the 110-111 (6 cm) and 211-212 (2 cm) transitions of ortho-formaldehyde (o-H2CO) in absorption at z=0.68466 toward the gravitational lens system B0218…
