Radio signatures of AGN-wind-driven shocks in elliptical galaxies: From simulations to observations

Posted by klaurent July 25, 2025Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Haojie Xia, Haojie Xia, , , | Summary: We investigate the synchrotron emission signatures of shocks driven by active galactic nucleus (AGN) wind in elliptical galaxies based on our two-dimensional axisymmetric hydrodynamic $textitMACER$ numerical simulations. Using these simulation data, we calculate the synchrotron radiation produced by nonthermal […]

Axonal defasciculation is restricted to specific branching points during regeneration of the lateral line nerve in zebrafish

Posted by dbos July 25, 2025August 4, 2025Rockefeller

Kavli Affiliate: A. James Hudspeth | Authors: Rohan S Roy and A. J. Hudspeth | Summary: Peripheral nerve regeneration requires precise selection of the appropriate targets of innervation, often in an environment that differs from that during the developmental wiring of the neural circuit. Severed axons of the zebrafish posterior lateral line nerve have the […]

A Systematic Search for Big Dippers in ASAS-SN

Posted by klaurent July 25, 2025Peking

Kavli Affiliate: Subo Dong | First 5 Authors: B. JoHantgen, B. JoHantgen, , , | Summary: Dipper stars are extrinsically variable stars with deep dimming events due to extended, often dusty, structures produced by a wide range of mechanisms such as collisions, protoplanetary evolution or stellar winds. ASAS-SN has discovered 12 dipper-like objects as part […]

First Temperature Profile of a Stellar Flare using Differential Chromatic Refraction

Posted by klaurent July 25, 2025Stanford

Kavli Affiliate: Aaron Roodman | First 5 Authors: Riley Clarke, Riley Clarke, , , | Summary: We present the first derivation of a stellar flare temperature profile from single-band photometry. Stellar flare DWF030225.574-545707.45129 was detected in 2015 by the Dark Energy Camera as part of the Deeper, Wider, Faster Programme. The brightness ($Delta m_g = […]

GATOS. n. On the physical origin of the extended MIR emission in AGN

Posted by klaurent July 25, 2025August 4, 2025Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Enrique Lopez-Rodriguez, Enrique Lopez-Rodriguez, , , | Summary: The polar mid-infrared (MIR) emission detected from tens to hundreds of parsecs in some active galactic nuclei (AGN) has been associated with dusty winds driven away by radiation pressure. However, the physical characterization of this extended polar emission remains […]

Silicate clouds and a circumplanetary disk in the YSES-1 exoplanet system

Posted by klaurent July 25, 2025August 4, 2025Stanford

Kavli Affiliate: Bruce Macintosh | First 5 Authors: , , , , | Summary: Young exoplanets provide a critical link between understanding planet formation and atmospheric evolution. Direct imaging spectroscopy allows us to infer the properties of young, wide orbit, giant planets with high signal-to-noise. This allows us to compare this young population to exoplanets […]
