JWST reveals the diversity of nuclear obscuring dust in nearby AGN: nuclear isolation of MIRI/MRS datacubes and continuum spectral fitting

Posted by klaurent April 1, 2025April 14, 2025Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Omaira González-Martín, Daniel J. Díaz-González, Mariela Martínez-Paredes, Almudena Alonso-Herrero, Enrique López-Rodríguez | Summary: We investigate the capabilities of the mid-infrared instrument (MIRI) of James Webb Space Telescope (JWST) to advance our knowledge of AGN dust using the spectral fitting technique on an AGN collection of 21 nearby […]

Understanding the Baryon Cycle: Fueling Star Formation via Inflows in Milky Way-like Galaxies

Posted by klaurent April 1, 2025April 14, 2025MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Filippo Barbani, Raffaele Pascale, Federico Marinacci, Paul Torrey, Laura V. Sales | Summary: Galaxies are not isolated systems; they continuously interact with their surroundings by ejecting gas via stellar feedback and accreting gas from the environment. Understanding the interplay between outflows from the disc and the surrounding […]

Formation and Environmental Context of Giant Bulgeless Disk Galaxies in the Early Universe: Insights from Cosmological Simulations

Posted by klaurent April 1, 2025Peking

Kavli Affiliate: Yingjie Peng | First 5 Authors: Fangzhou Jiang, Fangzhou Jiang, , , | Summary: Giant bulgeless disk galaxies, theoretically expected to be rare in the early Universe, have been confirmed by the James Webb Space Telescope (JWST) to exist as early as 2 billion years after the Big Bang. These morphologically extreme systems […]

Identifying biases of the Majorana scattering invariant

Posted by klaurent April 1, 2025Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: , , , , | Summary: The easily accessible experimental signatures of Majorana modes are ambiguous and only probe topology indirectly: for example, quasi-Majorana states mimic most properties of Majoranas. Establishing a correspondence between an experiment and a theoretical model known to be topological resolves this ambiguity. […]

A neutral hydrogen absorption study of cold gas in the outskirts of the Magellanic Clouds using the GASKAP-HI survey

Posted by klaurent April 1, 2025April 14, 2025Stanford

Kavli Affiliate: Susan E. Clark | First 5 Authors: Hongxing Chen, Snežana Stanimirović, Nickolas M. Pingel, James Dempsey, Frances Buckland-Willis | Summary: Cold neutral hydrogen (HI) is a crucial precursor for molecular gas formation and can be studied via HI absorption. This study investigates HI absorption in low column density regions of the Small and […]

Towards Calibrating Financial Market Simulators with High-frequency Data

Posted by klaurent April 1, 2025April 14, 2025Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Peng Yang, Junji Ren, Feng Wang, Ke Tang, | Summary: The fidelity of financial market simulation is restricted by the so-called "non-identifiability" difficulty when calibrating high-frequency data. This paper first analyzes the inherent loss of data information in this difficulty, and proposes to use the Kolmogorov-Smirnov test […]

Effects of chemically homogeneous evolution of the first stars on the 21-cm signal and reionization

Posted by klaurent April 1, 2025Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: , , , , | Summary: The first generation of stars, known as Population III (Pop III), played a crucial role in the early Universe through their unique formation environment and metal-free composition. These stars can undergo chemically homogeneous evolution (CHE) due to fast rotation, becoming more […]

A dual-scale stochastic analysis framework for creep failure considering microstructural randomness

Posted by klaurent April 1, 2025April 14, 2025Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Weichen Kong, Yanwei Dai, Xiang Zhang, Yinghua Liu, | Summary: Creep failure under high temperatures is a complex multiscale and multi-mechanism issue involving inherent microstructural randomness. To investigate the effect of microstructures on the uniaxial/multiaxial creep failure, a dual-scale stochastic analysis framework is established to introduce the […]

Polarization Position Angle Swing and the Rotating Vector Model of Repeating Fast Radio Bursts

Posted by klaurent April 1, 2025April 14, 2025Peking

Kavli Affiliate: Kejia Lee | First 5 Authors: Xiaohui Liu, Heng Xu, Jiarui Niu, Yongkun Zhang, Jinchen Jiang | Summary: Fast radio bursts (FRBs), typically highly polarized, usually have a nearly constant polarization position angle (PA) during each burst. Some bursts show significant PA variations, and one of them was claimed to have a PA […]
