Evaluating probabilistic and data-driven inference models for fiber-coupled NV-diamond temperature sensors

Posted by dbos Stanford

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Shraddha Rajpal, Zeeshan Ahmed, Tyrus Berry, , | Summary: We evaluate the impact of inference model on uncertainties when using continuous wave Optically Detected Magnetic Resonance (ODMR) measurements to infer temperature. Our approach leverages a probabilistic feedforward inference model designed to maximize the likelihood of observed ODMR […]

OPUS: Occupancy Prediction Using a Sparse Set

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Jiabao Wang, Zhaojiang Liu, Qiang Meng, Liujiang Yan, Ke Wang | Summary: Occupancy prediction, aiming at predicting the occupancy status within voxelized 3D environment, is quickly gaining momentum within the autonomous driving community. Mainstream occupancy prediction works first discretize the 3D environment into voxels, then perform classification […]

A Two-zone Accretion Disk in the Changing-look Active Galactic Nucleus 1ES 1927+654: Physical Implications for Tidal Disruption Events and Super-Eddington Accretion

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Ruancun Li, Luis C. Ho, Claudio Ricci, Benny Trakhtenbrot, | Summary: The properties of slim accretion disks, while crucial for our understanding of black hole growth, have yet to be studied extensively observationally. We analyze the multi-epoch broad-band spectral energy distribution of the changing-look active galactic […]

The Interplay between the Disk and Corona of the Changing-look Active Galactic Nucleus 1ES 1927+654

Posted by dbos MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Ruancun Li, Claudio Ricci, Luis C. Ho, Benny Trakhtenbrot, Erin Kara | Summary: Time-domain studies of active galactic nuclei (AGNs) offer a powerful tool for understanding black hole accretion physics. Prior to the optical outburst on 23 December 2017, 1ES 1927+654 was classified as a "true" type~2 […]

AGN STORM 2. VII. A Frequency-resolved Map of the Accretion Disk in Mrk 817: Simultaneous X-ray Reverberation and UVOIR Disk Reprocessing Time Lags

Posted by dbos MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Collin Lewin, Erin Kara, Aaron J. Barth, Edward M. Cackett, Gisella De Rosa | Summary: X-ray reverberation mapping is a powerful technique for probing the innermost accretion disk, whereas continuum reverberation mapping in the UV, optical, and infrared (UVOIR) reveals reprocessing by the rest of the accretion […]

The overestimation of equipartition magnetic field strengths from synchrotron emission using synthetically observed galaxies

Posted by dbos Stanford

Kavli Affiliate: Susan E. Clark | First 5 Authors: Tara Dacunha, Sergio Martin-Alvarez, Susan E. Clark, Enrique Lopez-Rodriguez, | Summary: Understanding the role that magnetic fields play on the stage of galaxy formation requires accurate methods for inferring the properties of extragalactic magnetic fields. Radio synchrotron emission has been the most promising avenue to infer […]

Constraining atmospheric composition from the outflow: helium observations reveal the fundamental properties of two planets straddling the radius gap

Posted by dbos MIT

Kavli Affiliate: Avi Shporer | First 5 Authors: Michael Zhang, Jacob L. Bean, David Wilson, Girish Duvvuri, Christian Schneider | Summary: TOI-836 is a $sim2-3$ Gyr K dwarf with an inner super Earth ($R=1.7,R_oplus$, $P=3.8,d$) and an outer mini Neptune ($R=2.6,R_oplus$, $P=8.6,d$). Recent JWST/NIRSpec 2.8–5.2 $mu$m observations have revealed flat transmission spectra for both planets. […]
