Independent Evidence for earlier formation epochs of fossil groups of galaxies through the intracluster light: the case for RX J100742.53+380046.6

Posted by klaurent MIT

Kavli Affiliate: Eric Miller | First 5 Authors: Renato A. Dupke, Yolanda Jimenez-teja, Yuanyuan Su, Eleazar R. Carrasco, Anton M. Koekemoer | Summary: Fossil groups (FG) of galaxies still present a puzzle to theories of structure formation. Despite the low number of bright galaxies, they have relatively high velocity dispersions and ICM temperatures often corresponding […]

Hard X-ray emission from the eastern jet of SS 433 powering the W50 `Manatee’ nebula: Evidence for particle re-acceleration

Posted by dbos MIT

Kavli Affiliate: Melania Nynka | First 5 Authors: Samar Safi-Harb, Brydyn Mac Intyre, Shuo Zhang, Isaac Pope, Shuhan Zhang | Summary: We present a broadband X-ray study of W50 (`the Manatee nebula’), the complex region powered by the microquasar SS 433, that provides a test-bed for several important astrophysical processes. The W50 nebula, a Galactic […]

Learning to correct spectral methods for simulating turbulent flows

Posted by klaurent Harvard

Kavli Affiliate: Michael P. Brenner | First 5 Authors: Gideon Dresdner, Dmitrii Kochkov, Peter Norgaard, Leonardo Zepeda-Núñez, Jamie A. Smith | Summary: Despite their ubiquity throughout science and engineering, only a handful of partial differential equations (PDEs) have analytical, or closed-form solutions. This motivates a vast amount of classical work on numerical simulation of PDEs […]

Search for a dark photon and an invisible dark Higgs boson in $μ^+μ^-$ and missing energy final states with the Belle II experiment

Posted by klaurent Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, L. Aggarwal, H. Aihara | Summary: The dark photon $A^prime$ and the dark Higgs boson $h^prime$ are hypothetical particles predicted in many dark sector models. We search for the simultaneous production of $A^prime$ and $h^prime$ in the dark Higgsstrahlung process […]

WS-Snapshot: An effective algorithm for wide-field and large-scale imaging

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Yangfan Xie, Feng Wang, Hui Deng, Ying Mei, Ying-He Celeste Lu | Summary: The Square Kilometre Array (SKA) is the largest radio interferometer under construction in the world. The high accuracy, wide-field and large size imaging significantly challenge the construction of the Science Data Processor (SDP) of […]

Reading and Writing: Discriminative and Generative Modeling for Self-Supervised Text Recognition

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Mingkun Yang, Minghui Liao, Pu Lu, Jing Wang, Shenggao Zhu | Summary: Existing text recognition methods usually need large-scale training data. Most of them rely on synthetic training data due to the lack of annotated real images. However, there is a domain gap between the synthetic data […]
