Radio Astrometry Of The Close Active Binary HR5110
Evan Abbuhl, Robert Mutel, Christene Lynch +1
The close active binary HR 5110 was observed at six epochs over 26 days using a global VLBI array at 15.4~GHz. We used phase-referencing to determine the position of the radio cent…
The Unusual Galactic Center Radio Source N3
Dominic A. Ludovici, Cornelia C. Lang, Mark R. Morris +4
Here we report on new, multi-wavelength radio observations of the unusual point source "N3" that appears to be located in the vicinity of the Galactic Center. VLA observations betw…
A Linear Relation Between the Color Stretch and the Rising Color Slope of Type Ia Supernovae
Ping Chen, Subo Dong, Chris Ashall +34
Using data from the Complete Nearby () sample of Type Ia Supernovae (CNIa0.02), we discover a linear relation between two parameters derived from the color cur…
Meter- to Millimeter Emission from Cool Stellar Systems: Latest Results, Synergies Across the Spectrum, and Outlook for the Next Decade
Jan Forbrich, Peter K. G. Williams, Emily Drabek-Maunder +12
Radio observations of cool stellar systems provide unique information on their magnetic fields, high-energy processes, and chemistry. Buoyed by powerful new instruments (e.g. ALMA,…
Gaia17biu/SN 2017egm in NGC 3191: The closest hydrogen-poor superluminous supernova to date is in a "normal", massive, metal-rich spiral galaxy
Subhash Bose, Subo Dong, A. Pastorello +55
Hydrogen-poor superluminous supernovae (SLSNe-I) have been predominantly found in low-metallicity, star-forming dwarf galaxies. Here we identify Gaia17biu/SN 2017egm as an SLSN-I o…
ASASSN-18am/SN 2018gk : An overluminous Type IIb supernova from a massive progenitor
Subhash Bose, Subo Dong, C. S. Kochanek +29
ASASSN-18am/SN 2018gk is a newly discovered member of the rare group of luminous, hydrogen-rich supernovae (SNe) with a peak absolute magnitude of mag that is in…
First Resolution of Microlensed Images
Subo Dong, A. Mérand, F. Delplancke-Ströbele +12
We employ VLTI GRAVITY to resolve, for the first time, the two images generated by a gravitational microlens. The measurements of the image separation θ_{-,+}=3.78 +/- 0.05 mas, a…
The First Data Release of CNIa0.02 -- A Complete Nearby (Redshift <0.02) Sample of Type Ia Supernova Light Curves
Ping Chen, Subo Dong, C. S. Kochanek +41
The CNIa0.02 project aims to collect a complete, nearby sample of Type Ia supernovae (SNe Ia) light curves, and the SNe are volume-limited with host-galaxy redshifts z_host < 0.02.…
Spitzer + VLTI-GRAVITY Measure the Lens Mass of a Nearby Microlensing Event
Weicheng Zang, Subo Dong, Andrew Gould +24
We report the lens mass and distance measurements of the nearby microlensing event TCP J05074264+2447555. We measure the microlens parallax vector using Spitzer and gr…
