Radiative feedback on supermassive star formation: the massive end of the Population III initial mass function

Posted by klaurent Peking

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Daisuke Toyouchi, Kohei Inayoshi, Wenxiu Li, Zoltán Haiman, Rolf Kuiper | Summary: Supermassive stars (SMSs) with masses of $M_ast simeq 10^4$–$10^5~{rm M_odot}$ are invoked as possible seeds of high-redshift supermassive black holes, but it remains under debate whether their protostar indeed acquires sufficient mass via gas accretion […]

High-resolution magic angle spinning NMR of KcsA in liposomes: the highly mobile C-terminus

Posted by klaurent Columbia

Kavli Affiliate: Ann McDermott | Authors: Ann E McDermott and Gary Stanley Howarth II | Summary: The structure of the transmembrane domain of bacterial potassium channel KcsA has been extensively characterized, yet little information is available on the structure of its cytosolic N- and C-termini. This study presents high-resolution magic angle spinning (HR-MAS) and fractional […]

Quantitative prediction and measurement of Piezo’s membrane footprint

Posted by klaurent Rockefeller

Kavli Affiliate: Roderick MacKinnon | Authors: Christoph A. Haselwandter, Roderick MacKinnon, Yusong Guo and Ziao Fu | Summary: Piezo proteins are mechanosensitive ion channels that can locally curve the membrane into a dome shape (Y. R. Guo, R. MacKinnon, 2017). The curved shape of the Piezo dome is expected to deform the surrounding lipid bilayer […]

Global worming: massive invasion of North America by earthworms revealed

Posted by klaurent UCSD / Salk

Kavli Affiliate: John Reynolds | Authors: Jerome Mathieu, John Warren Reynolds, Carlos Fragoso and Elizabeth Hadly | Summary: Human activities cause major ecological changes by reshuffling the spatial distribution of species. The extent to which this process affects belowground biota is a critical issue because soil organisms play a key role in ecosystem functioning and […]

Black holes: Timing and spectral properties and evolution

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Emrah Kalemci, Erin Kara, John A. Tomsick, , | Summary: We review the timing and spectral evolution of black hole X-ray binary systems, with emphasis on the current accretion-ejection paradigm. When in outburst, stellar mass black hole binaries may become the brightest X-ray sources in the sky. […]

The TESS-Keck Survey. XIII. An Eccentric Hot Neptune with a Similar-Mass Outer Companion around TOI-1272

Posted by klaurent MIT

Kavli Affiliate: Roland K. Vanderspek | First 5 Authors: Mason G. MacDougall, Erik A. Petigura, Tara Fetherolf, Corey Beard, Jack Lubin | Summary: We report the discovery of an eccentric hot Neptune and a non-transiting outer planet around TOI-1272. We identified the eccentricity of the inner planet, with an orbital period of 3.3 d and […]

Unveiling Time-Varying Signals of Ultralight Bosonic Dark Matter at Collider and Beam Dump Experiments

Posted by klaurent Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Jinhui Guo, Yuxuan He, Jia Liu, Xiao-Ping Wang, Ke-Pan Xie | Summary: The ultralight boson represents a promising dark matter candidate exhibiting unique wave-like behaviors. These properties could transfer to the dark mediator, such as the kinetic mixing dark photon, which can be a link between the […]

Time-varying resonant mass at collider and beam dump experiments

Posted by klaurent Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Jinhui Guo, Yuxuan He, Jia Liu, Xiao-Ping Wang, Ke-Pan Xie | Summary: A new particle usually manifests itself as a single resonant peak located at its mass. We propose if the new particle mass is time-varying due to environmental effects, then its mass spectrum typically has a […]
