Follow-up Observations of the Prolonged, super-Eddington, Tidal Disruption Event Candidate 3XMM~J150052.0+015452: the Slow Decline Continues
Dacheng Lin, Olivier Godet, Natalie A. Webb +7
The X-ray source 3XMM~J150052.0+015452 was discovered as a spectacular tidal disruption event candidate during a prolonged ( yrs) outburst (Lin et al. 2017). It exhibited uniq…
A luminous X-ray outburst from an intermediate-mass black hole in an off-centre star cluster
Dacheng Lin, Jay Strader, Eleazar R. Carrasco +13
A unique signature for the presence of massive black holes in very dense stellar regions is occasional giant-amplitude outbursts of multiwavelength radiation from tidal disruption…
Multiwavelength Follow-up Observations of the Tidal Disruption Event Candidate 2XMMi J184725.1-631724
Dacheng Lin, Jay Strader, Eleazar R. Carrasco +5
The ultrasoft X-ray flare 2XMMi J184725.1-631724 was serendipitously detected in two XMM-Newton observations in 2006 and 2007, with a peak luminosity of 6X10^43 erg/s. It was sugge…
A likely decade-long sustained tidal disruption event
Dacheng Lin, James Guillochon, S. Komossa +11
Multiwavelength flares from tidal disruption and accretion of stars can be used to find and study otherwise dormant massive black holes in galactic nuclei. Previous well-monitored…
Discovery of the Candidate Off-nuclear Ultrasoft Hyper-luminous X-ray Source 3XMM J141711.1+522541
Dacheng Lin, Eleazar R. Carrasco, Natalie A. Webb +8
We report the discovery of an off-nuclear ultrasoft hyper-luminous X-ray source candidate 3XMM J141711.1+522541 in the inactive S0 galaxy SDSS J141711.07+522540.8 (z=0.41827, d_L=2…
Discovery of an Ultrasoft X-ray Transient Source in the 2XMM Catalog: a Tidal Disruption Event Candidate
Dacheng Lin, Eleazar R. Carrasco, Dirk Grupe +3
We have discovered an ultrasoft X-ray transient source, 2XMMi J184725.1-631724, which was detected serendipitously in two XMM-Newton observations in the direction of the center of…
