A Potential Second Shutoff from AT2018fyk: An updated Orbital Ephemeris of the Surviving Star under the Repeating Partial Tidal Disruption Event Paradigm

Posted by dbos MIT

Kavli Affiliate: Dheeraj Pasham | First 5 Authors: Dheeraj Pasham, Eric Coughlin, Muryel Guolo, Thomas Wevers, Chris Nixon | Summary: The tidal disruption event (TDE) AT2018dyk/ASASSN-18UL showed a rapid dimming event 500 days after discovery, followed by a re-brightening roughly 700 days later. It has been hypothesized that this behavior results from a repeating partial […]

Emergence of a radio jet in the changing-look AGN 1ES 1927+654

Posted by dbos MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Eileen T. Meyer, Sibasish Laha, Onic I. Shuvo, Agniva Roychowdhury, David A. Green | Summary: We present multi-frequency (5-345 GHz) and multi-resolution radio observations of 1ES 1927+654, widely considered one of the most unusual and extreme changing-look active galactic nuclei (CL-AGN). The source was first designated a […]

A high-resolution imaging survey of massive young stellar objects in the Magellanic Clouds

Posted by dbos Peking

Kavli Affiliate: Gregory Herczeg | First 5 Authors: Venu M. Kalari, Ricardo Salinas, Hans Zinnecker, Monica Rubio, Gregory Herczeg | Summary: Constraints on the binary fraction of young massive stellar objects (mYSOs) are important for binary and massive star formation theory. Here, we present speckle imaging of 34 mYSOs located in the Large (1/2 $Z_{odot}$) […]

Correlated mid-infrared and X-ray outbursts in black hole X-ray binaries: A new route to discovery in infrared surveys

Posted by dbos MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Chris John, Kishalay De, Matteo Lucchini, Ehud Behar, Erin Kara | Summary: The mid-infrared (MIR; $lambdasimeq3 – 10mu$m) bands offer a unique window into understanding accretion and its interplay with jet formation in Galactic black hole X-ray binaries (BHXRBs). Although extremely difficult to observe from the ground, […]

The hyperplane of early-type galaxies: using stellar population properties to increase the precision and accuracy of the fundamental plane as a distance indicator

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Francesco D’Eugenio, Matthew Colless, Arjen van der Wel, Sam P. Vaughan, Khaled Said | Summary: We use deep spectroscopy from the SAMI Galaxy Survey to explore the precision of the fundamental plane of early-type galaxies (FP) as a distance indicator for future single-fibre spectroscopy surveys. We study […]

Prior-Informed AGN-Host Spectral Decomposition Using PyQSOFit

Posted by dbos Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Wenke Ren, Hengxiao Guo, Yue Shen, John D. Silverman, Colin J. Burke | Summary: We introduce an improved method for decomposing the emission of active galactic nuclei (AGN) and their host galaxies using templates from principal component analysis (PCA). This approach integrates prior information from PCA […]

Gravitational waves from mergers of Population III binary black holes: roles played by two evolution channels

Posted by dbos Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Boyuan Liu, Tilman Hartwig, Nina S. Sartorio, Irina Dvorkin, Guglielmo Costa | Summary: The gravitational wave (GW) signal from binary black hole (BBH) mergers is a promising probe of Population III (Pop III) stars. To fully unleash the power of the GW probe, one important step is […]
