Plausible home stars of the interstellar object 'Oumuamua found in Gaia DR2
C. A. L. Bailer-Jones, D. Farnocchia, K. J. Meech +5
The first detected interstellar object 'Oumuamua that passed within 0.25au of the Sun on 2017 September 9 was presumably ejected from a stellar system. We use its newly determined…
Relating the HI Gas Structure of Spiral Disks to Passing Satellites
Andrew Lipnicky, Sukanya Chakrabarti, Philip Chang
We extend the work of Chang & Chakrabarti (2011) to find simple scaling relations between the density response of the gas disk of a spiral galaxy and the pericenter distance and ma…
The supernova rate beyond the optical radius
Sukanya Chakrabarti, Brennan Dell, Or Graur +3
Many spiral galaxies have extended outer H~I disks and display low levels of star formation, inferred from the far-ultraviolet emission detected by {\it GALEX}, well beyond the opt…
The First Detection of Neutral Hydrogen in Emission in a Strong Spiral Lens
Andrew Lipnicky, Sukanya Chakrabarti, Melvyn C. H. Wright +7
We report HI observations of eight spiral galaxies that are strongly lensing background sources. Our targets were selected from the Sloan WFC (Wide Field Camera) Edge-on Late-type…
