A demonstration of the effect of fringe-rate filtering in the Hydrogen Epoch of Reionization Array delay power spectrum pipeline

Posted by klaurent MIT

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Hugh Garsden, Philip Bull, Mike Wilensky, Zuhra Abdurashidova, Tyrone Adams | Summary: Radio interferometers targeting the 21cm brightness temperature fluctuations at high redshift are subject to systematic effects that operate over a range of different timescales. These can be isolated by designing appropriate Fourier filters that […]

Learning Continuous 3D Words for Text-to-Image Generation

Posted by klaurent UCSB

Kavli Affiliate: Matthew Fisher | First 5 Authors: Ta-Ying Cheng, Matheus Gadelha, Thibault Groueix, Matthew Fisher, Radomir Mech | Summary: Current controls over diffusion models (e.g., through text or ControlNet) for image generation fall short in recognizing abstract, continuous attributes like illumination direction or non-rigid shape change. In this paper, we present an approach for […]

Tuning the Spin Interaction in Non-planar Organic Diradicals Through Mechanical Manipulation

Posted by klaurent Delft

Kavli Affiliate: Herre S. J. Van Der Zant | First 5 Authors: Alessio Vegliante, Saleta Fernandez, Ricardo Ortiz, Manuel Vilas-Varela, Thomas Baum | Summary: Open-shell polycyclic aromatic hydrocarbons (PAHs) represent promising building blocks for carbon-based functional magnetic materials. Their magnetic properties stem from the presence of unpaired electrons localized in radical states of $pi$ character. […]

Tracking topological defect motion and incommensurate charge order melting in a perovskite manganite

Posted by klaurent Cornell

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Noah Schnitzer, Berit H. Goodge, Gregory Powers, Jaewook Kim, Sang-Wook Cheong | Summary: Charge order pervades the phase diagrams of many quantum materials where it competes with superconducting and magnetic phases, hosts electronic phase transitions and topological defects, and couples to the lattice generating intricate structural […]

Evidence for flare-accelerated particles in large scale loops in the behind-the-limb gamma-ray solar flare of September 29, 2022

Posted by klaurent Stanford

Kavli Affiliate: Nicola Omodei | First 5 Authors: Melissa Pesce-Rollins, Karl-Ludwig Klein, Säm Krucker, Alexander Warmuth, M. Astrid Veronig | Summary: We report on the detection of the gamma-ray emission above 100 MeV from the solar flare of September 29, 2022, by Fermi LAT with simultaneous coverage in HXR by Solar Orbiter STIX. The Solar […]

High-cadence Timing of Binary Pulsars with CHIME

Posted by klaurent MIT

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Chia Min Tan, Emmanuel Fonseca, Kathryn Crowter, Fengqiu Adam Dong, Victoria M. Kaspi | Summary: We performed near-daily observations on the binary pulsars PSR J0218+4232, PSR J1518+4904 and PSR J2023+2853 with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). For the first time, we detected the Shapiro […]

Unselfish meiotic drive maintains heterozygosity in a parthenogenetic ant

Posted by klaurent Rockefeller

Kavli Affiliate: Daniel Kronauer | Authors: Kip D Lacy, Taylor Hart and Daniel J.C. Kronauer | Summary: According to Mendel’s second law, chromosomes segregate randomly in meiosis. Non-random segregation is primarily known for cases of selfish meiotic drive in females, in which particular alleles bias their own transmission into the oocyte1,2. Here, we report a […]

How the Galaxy-Halo Connection Depends on Large-Scale Environment

Posted by klaurent Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: John F. Wu, Christian Kragh Jespersen, Risa H. Wechsler, , | Summary: We investigate the connection between galaxies, dark matter halos, and their large-scale environments with Illustris TNG300 hydrodynamic simulation data. We predict stellar masses from subhalo properties to test two types of machine learning (ML) […]

Ephemeris Matching Reveals False Positive Validated and Candidate Planets from the K2 Mission

Posted by klaurent MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Drake A. Lehmann, Andrew Vanderburg, , , | Summary: Data from the Kepler space telescope have led to the discovery of thousands of planet candidates. Most of these candidates are likely to be real exoplanets, but a significant number of false positives still contaminate the sample, especially […]
