An ultraviolet excess in the superluminous supernova Gaia16apd reveals a powerful central engine
M. Nicholl, E. Berger, R. Margutti +5
Since the discovery of superluminous supernovae (SLSNe) in the last decade, it has been known that these events exhibit bluer spectral energy distributions than other supernova sub…
Variable and polarized radio emission from the T6 brown dwarf WISEP J112254.73+255021.5
P. K. G. Williams, J. E. Gizis, E. Berger
Route & Wolszczan (2016) recently detected five radio bursts from the T6 dwarf WISEP J112254.73+255021.5 and used the timing of these events to propose that this object rotates wit…
M Dwarf Activity in the Pan-STARRS 1 Medium-Deep Survey: First Catalog and Rotation Periods
Erin Kado-Fong, Peter K. G. Williams, Andrew W. Mann +9
We report on an ongoing project to investigate activity in the M dwarf stellar population observed by the Pan-STARRS 1 Medium Deep Survey (PS1-MDS). Using a custom-built pipeline,…
The Intermediate Luminosity Optical Transient SN 2010da: The Progenitor, Eruption and Aftermath of a Peculiar Supergiant High-mass X-ray Binary
V. Ashley Villar, Edo Berger, Ryan Chornock +7
We present optical spectroscopy, ultraviolet to infrared imaging and X-ray observations of the intermediate luminosity optical transient (ILOT) SN 2010da in NGC 300 (d=1.86 Mpc) sp…
The First Millimeter Detection of a Non-Accreting Ultracool Dwarf
P. K. G. Williams, S. L. Casewell, C. R. Stark +3
The well-studied M9 dwarf TVLM 513-46546 is a rapid rotator (P_rot ~ 2 hr) hosting a stable, dipolar magnetic field of ~3 kG surface strength. Here we report its detection with ALM…
The Rotation Period and Magnetic Field of the T Dwarf 2MASSI J1047539+212423 Measured From Periodic Radio Bursts
P. K. G. Williams, E. Berger
Periodic radio bursts from very low mass stars and brown dwarfs simultaneously probe their magnetic and rotational properties. The brown dwarf 2MASSI J1047539+212423 (2M 1047+21) i…
