Survey of Ionized Gas of the Galaxy, Made with the Arecibo telescope (SIGGMA): Inner Galaxy Data Release
Bin Liu, L. D. Anderson, Travis McIntyre +4
The Survey of Ionized Gas of the Galaxy, Made with the Arecibo telescope (SIGGMA) provides a fully-sampled view of the radio recombination line (RRL) emission from the portion of t…
A Probabilistic Analysis of the Fermi Paradox
Evan Solomonides, Yervant Terzian
The fermi paradox uses an appeal to the mediocrity principle to make it seem counter-intuitive that humanity has not been contacted by extraterrestrial intelligence. A numerical, s…
A Search for Dust Emission in the Leo Intergalactic Cloud
C. Bot, G. Helou, W. B. Latter +3
We present a search for infrared dust emission associated with the Leo cloud, a large intergalactic cloud in the M96 group. Mid-infrared and far-infrared images were obtained with…
Hubble Space Telescope Expansion Parallaxes of the Planetary Nebulae NGC 6578, NGC 6884, NGC 6891, and IC 2448
Stacy Palen, Bruce Balick, Arsen R. Hajian +3
We have combined two epochs of Hubble Space Telescope WFPC2 imaging data with ground-based expansion velocities to determine distances to three planetary nebulae (NGC 6578, NGC 688…
HST Measurements of the Expansion of NGC 6543: Parallax Distance and Nebular Evolution
D. S. Reed, B. Balick, A. R. Hajian +5
The optical expansion parallax of NGC 6543 has been detected and measured using two epochs of HST images separated by a time baseline of only three years. We have utilized three se…
