Strong Lensing analysis of SPT-CLJ2325$-$4111 and SPT-CLJ0049$-$2440, two Powerful Cosmic Telescopes ($R_E > 40”$) from the SPT Clusters Sample

Posted by dbos January 6, 2025Chicago

Kavli Affiliate: Lindsey E. Bleem | First 5 Authors: Guillaume Mahler, Keren Sharon, Matthew Bayliss, Lindsey. E. Bleem, Mark Brodwin | Summary: We report the results from a study of two massive ($M_{500c} > 6.0 times 10^{14} M_{odot}$) strong lensing clusters selected from the South Pole Telescope cluster survey for their high Einstein radius ($R_E […]

Time-resolved Hubble Space Telescope UV observations of an X-ray quasi-periodic eruption source

Posted by klaurent January 6, 2025MIT

Kavli Affiliate: Dheeraj Pasham | Summary:X-ray quasi-periodic eruptions (QPEs) are a novel mode of variability in nearby galactic nuclei whose origin remains unknown. Their multi-wavelength properties are poorly constrained, as studies have focused almost entirely on the X-ray band. Here we report on time-resolved, coordinated Hubble Space Telescope far ultraviolet and XMM-Newton X-ray observations of […]

Clumps as multiscale structures in cosmic noon galaxies

Posted by dbos January 6, 2025Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Boris S Kalita, Tomoko L Suzuki, Daichi Kashino, John D Silverman, Emanuele Daddi | Summary: Star-forming clumps have been found to significantly influence the star formation of gas-rich $z>1$ galaxies. Using public data from JWST/NIRCam (COSMOS-Web) and ALMA (FMOS-COSMOS), we study a sample of 32 massive […]

A multi-wavelength investigation of spiral structures in $z > 1$ galaxies with JWST

Posted by dbos January 6, 2025Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Boris S. Kalita, Si-Yue Yu, John D. Silverman, Emanuele Daddi, Luis C. Ho | Summary: Recent JWST observations have revealed the prevalence of spiral structures at $z > 1$. Unlike in the local Universe, the origin and the consequence of spirals at this epoch remain unexplored. […]

The superior colliculus gates dopamine responses to conditioned stimuli in visual classical conditioning

Posted by dbos January 6, 2025January 13, 2025UCSD / Salk

Kavli Affiliate: John Reynolds | Authors: Yan-Feng Zhang, Jean-Philippe Dufour, Peter Zatka-Haas, Peter Redgrave, Melony J Black, Armin Lak, Ed Mann, Stephanie J Cragg, Wickliffe Abraham and John NJ Reynolds | Summary: In classical Pavlovian conditioning, it is well-established that midbrain dopamine neurons respond to conditioned stimuli (CS) that predict a reward. However, how the […]

Non-local modular flows across deformed null-cuts

Posted by klaurent January 6, 2025UCAS

Kavli Affiliate: Huajia Wang | Summary:Modular flows probe important aspects of the entanglement structures, especially those of QFTs, in a dynamical framework. Despite the expected non-local nature in the general cases, the majority of explicitly understood examples feature local space-time trajectories under modular flows. In this work, we study a particular class of non-local modular […]

Comprehensive Pathological Image Segmentation via Teacher Aggregation for Tumor Microenvironment Analysis

Posted by klaurent January 6, 2025Tokyo

Kavli Affiliate: Tomoyuki Abe| First 5 Authors: Daisuke Komura, Daisuke Komura, , , | Summary:The tumor microenvironment (TME) plays a crucial role in cancer progression and treatment response, yet current methods for its comprehensive analysis in H&E-stained tissue slides face significant limitations in the diversity of tissue cell types and accuracy. Here, we present PAGET […]

Topology meets time-reversal symmetry breaking in FeSe$_1-x$Te$_x$ superconductor

Posted by klaurent January 6, 2025Tokyo

Kavli Affiliate: Masaki Yamashita| First 5 Authors: M. Roppongi, M. Roppongi, , , | Summary:Time-reversal symmetry breaking (TRSB) in magnetic topological insulators induces a Dirac gap in the topological surface state (TSS), leading to exotic phenomena such as the quantum anomalous Hall effect. Yet, the interplay between TRSB and topology in superconductors remains underexplored due […]
