Image deconvolution and PSF reconstruction with STARRED: a wavelet-based two-channel method optimized for light curve extraction

Posted by klaurent Stanford

Kavli Affiliate: Philip J. Marshall | First 5 Authors: Martin Millon, Kevin Michalewicz, Frédéric Dux, Frédéric Courbin, Philip J. Marshall | Summary: We present STARRED, a Point Spread Function (PSF) reconstruction, two-channel deconvolution, and light curve extraction method designed for high-precision photometric measurements in imaging time series. An improved resolution of the data is targeted […]

Testing EMRI models for Quasi-Periodic Eruptions with 3.5 years of monitoring eRO-QPE1

Posted by dbos MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Joheen Chakraborty, Riccardo Arcodia, Erin Kara, Giovanni Miniutti, Margherita Giustini | Summary: Quasi-Periodic Eruptions (QPEs) are luminous X-ray outbursts recurring on hour timescales, observed from the nuclei of a growing handful of nearby low-mass galaxies. Their physical origin is still debated, and usually modeled as (a) accretion […]

Constraining neutrino-DM interactions with Milky Way dwarf spheroidals and supernova neutrinos

Posted by dbos Tokyo

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Sean Heston, Shunsaku Horiuchi, Satoshi Shirai, , | Summary: We constrain the neutrino-dark matter cross section using properties of the dark matter density profiles of Milky Way dwarf spheroidal galaxies. The constraint arises from core-collapse supernova neutrinos scattering on dark matter as a form of energy injection, […]

The THESAN project: galaxy sizes during the epoch of reionization

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Xuejian Shen, Mark Vogelsberger, Josh Borrow, Yongao Hu, Evan Erickson | Summary: We investigate galaxy sizes at redshift $zgtrsim 6$ with the cosmological radiation-magneto-hydrodynamic simulation suite THESAN(-HR). These simulations simultaneously capture the reionization of the large-scale intergalactic medium and resolved galaxy properties. The intrinsic size ($r^{ast}_{1/2}$) of […]

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 […]
