Cell Division and Motility Enable Hexatic Order in Biological Tissues

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Yiwen Tang, Siyuan Chen, Mark J. Bowick, Dapeng Bi, | Summary: Biological tissues transform between solid-like and liquid-like states in many fundamental physiological events. Recent experimental observations further suggest that in two-dimensional epithelial tissues these solid-liquid transformations can happen via intermediate states akin to the intermediate […]

Discovery of Orbital Ordering in Bi2Sr2CaCu2O8+x

Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Shuqiu Wang, Niall Kennedy, Kazuhiro Fujita, Shin-ichi Uchida, Hiroshi Eisaki | Summary: The primordial ingredient of cuprate superconductivity is the CuO2 unit cell. Here, theoretical attention usually concentrates on the intra-atom Coulombic interactions dominating the 3d^9 and 3d^10 configurations of each copper ion. However, if […]

Investigation of Cryogenic Current-Voltage Anomalies in SiGe HBTs: Role of Base-Emitter Junction Inhomogeneities

Kavli Affiliate: Austin J. Minnich | First 5 Authors: Nachiket R. Naik, Bekari Gabritchidze, Justin H. Chen, Jacob Kooi, Kieran A. Cleary | Summary: The deviations of cryogenic collector current-voltage characteristics of SiGe heterojunction bipolar transistors (HBTs) from ideal drift-diffusion theory have been a topic of investigation for many years. Recent work indicates that direct […]

Investigation of Cryogenic Current-Voltage Anomalies in SiGe HBTs: Role of Base-Emitter Junction Inhomogeneities

Kavli Affiliate: Austin J. Minnich | First 5 Authors: Nachiket R. Naik, Bekari Gabritchidze, Jacob Kooi, Kieran A. Cleary, Austin J. Minnich | Summary: The anomalous current-voltage characteristics of cryogenic SiGe heterojunction bipolar transistors (HBTs) have been a topic of investigation for many years. Proposed explanations include quasiballistic transport of electrons across the base or […]

A recently quenched galaxy 700 million years after the Big Bang

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Tobias J. Looser, Francesco D’Eugenio, Roberto Maiolino, Joris Witstok, Lester Sandles | Summary: Local and low-redshift ($z$<$3$) galaxies are known to broadly follow a bimodal distribution: actively star forming galaxies with relatively stable star-formation rates, and passive systems. These two populations are connected by galaxies in relatively […]

Primordial-tensor-induced stochastic gravitational waves

Kavli Affiliate: Misao Sasaki | First 5 Authors: Mohammad Ali Gorji, Misao Sasaki, , , | Summary: Cosmological stochastic gravitational waves (GWs) induced by a spectator field are usually expected to have an amplitude very small compared with those generated by the curvature perturbation, or equivalently by a field dominating the universe. On the contrary […]

DESI survey validation data in the COSMOS/HSC field: Cool gas trace main sequence star-forming galaxies at the cosmic noon

Kavli Affiliate: Linhua Jiang | First 5 Authors: Siwei Zou, Linhua Jiang, Zheng Cai, John Moustakas, Zechang Sun | Summary: We present the first result in exploring the gaseous halo and galaxy correlation using the Dark Energy Spectroscopic Instrument (DESI) survey validation data in the Cosmic Evolution Survey (COSMOS) and Hyper Suprime-Cam (HSC) field. We […]

Unusual Hard X-ray Flares Caught in NICER Monitoring of the Binary Supermassive Black Hole Candidate AT2019cuk/Tick Tock/SDSS J1430+2303

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Megan Masterson, Erin Kara, Dheeraj R. Pasham, Daniel J. D’Orazio, Dominic J. Walton | Summary: The nuclear transient AT2019cuk/Tick Tock/SDSS J1430+2303 has been suggested to harbor a supermassive black hole (SMBH) binary near coalescence. We report results from high-cadence NICER X-ray monitoring with multiple visits per […]

The interplay between accretion, galaxy downsizing and the formation of box/peanut bulges in TNG50

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Stuart Robert Anderson, Steven Gough-Kelly, Victor P. Debattista, Min Du, Peter Erwin | Summary: From the TNG50 cosmological simulation we build a sample of 191 well-resolved barred galaxies with a stellar mass $log M_star > 10$ at $z=0$. We search for box/peanut bulges (BPs) in this sample, […]
