Kavli Affiliate: Lina Necib | First 5 Authors: Shuyu Wang, Lina Necib, Alexander P. Ji, Xiaowei Ou, Mariangela Lisanti | Summary: Nyx is a nearby, prograde, and high-eccentricity stellar stream physically contained in the thick disk but with an unknown origin. Nyx could be the remnant of a disrupted dwarf galaxy, in which case the […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Michael Pagano, Jing Liu, Adrian Liu, Nicholas S. Kern, Aaron Ewall-Wice | Summary: Radio Frequency Interference (RFI) is one of the systematic challenges preventing 21cm interferometric instruments from detecting the Epoch of Reionization. To mitigate the effects of RFI on data analysis pipelines, numerous inpaint techniques […]

Kavli Affiliate: Xiang Zhang | First 5 Authors: Tianchun Wan, Wei Cheng, Dongsheng Luo, Wenchao Yu, Jingchao Ni | Summary: Personalized Federated Learning (PFL) which collaboratively trains a federated model while considering local clients under privacy constraints has attracted much attention. Despite its popularity, it has been observed that existing PFL approaches result in sub-optimal […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yi Zhou, Danushka Bollegala, , , | Summary: We show that the $ell_2$ norm of a static sense embedding encodes information related to the frequency of that sense in the training corpus used to learn the sense embeddings. This finding can be seen as an extension of […]
Kavli Affiliate: Jill Leutgeb | Authors: Silvia Viana da Silva, Matthias G Haberl, Kshitij Gaur, Rina Patel, Gautam Narayan, Max Ledakis, Maylin L. Fu, Edward H. Koo, Jill K. Leutgeb and Stefan Leutgeb | Summary: Abstract Deficits in spatial navigation are among the early symptoms in Alzheimer’s disease patients, consistent with the hippocampal formation as […]
Jenny E. Greene, Shany Danieli, Scott Carlsten, Rachael Beaton, Fangzhou Jiang | Summary: [[{“value”:”Isolated dwarf galaxies usually exhibit robust star formation but satellite dwarf galaxies are often devoid of young stars, even in Milky Way-mass groups. Dwarf galaxies thus offer an important laboratory of the environmental processes that cease star formation. We explore the balance […]
Shany Danieli, Jenny E. Greene, Scott Carlsten, Fangzhou Jiang, Rachael Beaton | Summary: [[{“value”:”Quantifying the connection between galaxies and their host dark matter halos has been key for testing cosmological models on various scales. Below $M_star sim 10^9,M_odot$, such studies have primarily relied on the satellite galaxy population orbiting the Milky Way. Here we present […]

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Zitao Lin, Tianjun Gan, Sharon X. Wang, Avi Shporer, Markus Rabus | Summary: We report the discovery of three transiting low-mass companions to aged stars: a brown dwarf (TOI-2336b) and two objects near the hydrogen burning mass limit (TOI-1608b and TOI-2521b). These three systems were first identified […]
