The Sloan Digital Sky Survey Reverberation Mapping Project: UV-Optical Accretion Disk Measurements with Hubble Space Telescope

Posted by klaurent Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Y. Homayouni, Megan R. Sturm, Jonathan R. Trump, Keith Horne, C. J. Grier | Summary: We present accretion-disk structure measurements from UV-optical reverberation mapping observations of a sample of eight quasars at 0.24<z<0.85. Ultraviolet photometry comes from two cycles of Hubble Space Telescope monitoring, accompanied by […]

The Polarized Image of a Synchrotron Emitting Ring of Gas Orbiting a Black Hole

Posted by Chicago

Kavli Affiliate: John E. Carlstrom | First 5 Authors: Ramesh Narayan, Daniel C. M. Palumbo, Michael D. Johnson, Zachary Gelles, Elizabeth Himwich | Summary: Synchrotron radiation from hot gas near a black hole results in a polarized image. The image polarization is determined by effects including the orientation of the magnetic field in the emitting […]

Ladder Symmetries of Black Holes: Implications for Love Numbers and No-Hair Theorems

Posted by klaurent Chicago

Kavli Affiliate: Austin Joyce | First 5 Authors: Lam Hui, Austin Joyce, Riccardo Penco, Luca Santoni, Adam R. Solomon | Summary: It is well known that asymptotically flat black holes in general relativity have a vanishing static, conservative tidal response. We show that this is a result of linearly realized symmetries governing static (spin 0,1,2) […]

Continuous measurement of a qudit using dispersively coupled radiation

Posted by klaurent Berkeley

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: John Steinmetz, Debmalya Das, Irfan Siddiqi, Andrew N. Jordan, | Summary: We analyze the continuous monitoring of a qudit coupled to a cavity using both phase-preserving and phase-sensitive amplification. The quantum trajectories of the system are described by a stochastic master equation, for which we derive the […]

Heritable differences in synaptic zinc-transporter levels drive variation in learned birdsong

Posted by klaurent UCSF

Kavli Affiliate: Michael Brainard | Authors: DG. Mets, W. H. Mehaffey, B. M. Colquitt and M. S. Brainard | Summary: Abstract The authors have withdrawn this manuscript. During revision of our manuscript, we carried out several lines of additional experiments and analyses that failed to fully support and reproduce the results previously presented in Figure […]
