Proposal for asymmetric photoemission and tunneling spectroscopies in quantum simulators of the triangular-lattice Fermi-Hubbard model

Posted by klaurent UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Shuai A. Chen, Qianqian Chen, Zheng Zhu, , | Summary: Recent realization of well-controlled quantum simulators of the triangular-lattice Fermi-Hubbard model, including the triangular optical lattices loaded with ultracold Fermions and the heterostructures of the transition-metal dichalcogenides, as well as the more advanced techniques to probe them, […]

A multiwavelength-motivated X-ray model for the Circinus Galaxy

Posted by klaurent Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Carolina Andonie, Claudio Ricci, Stéphane Paltani, Patricia Arévalo, Ezequiel Treister | Summary: Reprocessed X-ray emission in Active Galactic Nuclei (AGN) can provide fundamental information about the circumnuclear environments of supermassive black holes. Recent mid-infrared studies have shown evidence of an extended dusty structure perpendicular to the torus […]

Dissecting the different components of the modest accretion bursts of the very young protostar HOPS 373

Posted by klaurent Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Sung-Yong Yoon, Gregory J. Herczeg, Jeong-Eun Lee, Ho-Gyu Lee, Doug Johnstone | Summary: Observed changes in protostellar brightness can be complicated to interpret. In our JCMT~Transient monitoring survey, we discovered that a young binary protostar, HOPS 373, is undergoing a modest $30%$ brightness increase at 850 […]

Transient oscillations of neural firing rate associated with routing of evidence in a perceptual decision

Posted by klaurent Columbia

Kavli Affiliate: Michael Shadlen | Authors: Naomi N Odean, Mehdi Sanayei and Michael N Shadlen | Summary: Abstract To form a perceptual decision the brain must acquire samples of evidence from the environment and incorporate them in computations that mediate choice behavior. While much is known about the neural circuits that process sensory information and […]

Detection of a dense group of hyper-compact radio sources in the central parsec of the Galaxy

Posted by klaurent Stanford

Kavli Affiliate: R. Morris | First 5 Authors: Jun-Hui Zhao, Mark R. Morris, W. M. Goss, , | Summary: Using the JVLA, we explored the Galactic center (GC) with a resolution of 0.05" at 33.0 and 44.6 GHz. We detected 64 hyper-compact radio sources (HCRs) in the central parsec. The dense group of HCRs can […]

Luminosity function and event rate density of XMM-Newton-selected supernova shock-breakout candidates

Posted by klaurent Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: Hui Sun, He-Yang Liu, Haiwu Pan, Zhu Liu, Dennis Alp | Summary: A dozen X-ray supernova shock breakout (SN SBO) candidates were reported recently based on XMM-Newton archival data, which increased the X-ray selected SN SBO sample by an order of magnitude. Assuming they are genuine SN […]

The origin of the unfocused XMM-Newton background, its variability and lessons learned for ATHENA

Posted by klaurent MIT

Kavli Affiliate: Catherine E. Grant | First 5 Authors: Fabio Gastaldello, Martino Marelli, Silvano Molendi, Iacopo Bartalucci, Patrick Kühl | Summary: We analyzed the unexposed to the sky outFOV region of the MOS2 detector on board XMM-Newton covering 15 years of data amounting to 255 Ms. We show convincing evidence that the origin of the […]
