We present the Young Supernova Experiment Data Release 1 (YSE DR1), comprised of processed multi-color Pan-STARRS1 (PS1) griz and Zwicky Transient Facility (ZTF) gr photometry 1975 transients with host-galaxy associations, redshifts, spectroscopic/photometric classifications, additional data products from 2019 November 24 to 2021 December 20. YSE DR1 spans discoveries observations young fast-rising supernovae (SNe) that persist for over a year, redshift distribution reaching z~0.5. relative...
ABSTRACT We apply the hierarchical probabilistic spectral energy distribution (SED) model bayesn to analyse a sample of 475 type Ia supernovae (0.015 < z 0.4) from Foundation, DES3YR and PS1MD investigate properties dust in their host galaxies. jointly infer law RV population distributions at SED level high- low-mass galaxies simultaneously with dust-independent, intrinsic differences. find an mass step −0.049 ± 0.016 mag, significance 3.1σ, when allowing for constant intrinsic,...
We have measured the polarization, analyzing power, and depolarization parameter for forward ${\ensuremath{\Lambda}}^{0}'\mathrm{s}$ produced with a 6-GeV/c polarized-proton beam at Argonne National Laboratory zero-gradient synchrotron. collected sample of 15 281 ${\ensuremath{\Lambda}}^{0}$ production events subsequent $p{\ensuremath{\pi}}^{\ensuremath{-}}$ decays. There is clear difference between polarization power Feynman scaling variable $x$ greater than 0.8. This first observation this...
Abstract Strongly lensed supernovae (SNe) are a rare class of transient that can offer tight cosmological constraints complementary to methods from other astronomical events. We present follow-up study one recently discovered strongly SN, the quadruply imaged type Ia SN 2022qmx (aka “SN Zwicky”), at z = 0.3544. measure updated, template-subtracted photometry for Zwicky and derive improved time delays magnifications. This is possible because SNe transient, fading away after reaching their...
We introduce the rapidly emerging field of multi-messenger gravitational lensing - discovery and science gravitationally lensed phenomena in distant universe through combination multiple messengers. This is framed by phenomenology that has grown since first discoveries 20th century, messengers span 30 orders magnitude energy from high neutrinos to waves, powerful "survey facilities" are capable continually scanning sky for transient variable sources. Within this context, main focus on...

ABSTRACT We present gausSN, a Bayesian semiparametric Gaussian Process (GP) model for time-delay estimation with resolved systems of gravitationally lensed supernovae (glSNe). gausSN models the underlying light curve non-parametrically using GP. Without assuming template each SN type, fits time delays all images data in any number wavelength filters simultaneously. also introduce novel time-varying magnification to capture effects microlensing alongside estimation. In this analysis, we...
Context. Transient astronomical events that exhibit no discernible association with a host galaxy are commonly referred to as hostless. These rare phenomena associated extremely energetic events, and they can offer unique insights into the properties evolution of stars galaxies. However, sheer number transients captured by contemporary high-cadence surveys renders manual identification all potential hostless impractical. Therefore, creating systematic tool is crucial for studying these...

We present the MULTIMODAL UNIVERSE, a large-scale multimodal dataset of scientific astronomical data, compiled specifically to facilitate machine learning research. Overall, UNIVERSE contains hundreds millions observations, constituting 100\,TB multi-channel and hyper-spectral images, spectra, multivariate time series, as well wide variety associated measurements "metadata". In addition, we include range benchmark tasks representative standard practices for methods in astrophysics. This...
Abstract We present the Multimodal Universe , a new framework collating over 100 TB of multimodal astronomical data for its first release, spanning images, spectra, time series, tabular and hyper-spectral data.

A dual-band, fiber-optic, photon time-of-flight instrument was developed. Its design optimized for measuring the velocity of visible photons emanating from relatively dim astronomical sources (apparent magnitude m>12), such as distant galaxies and quasars. We report first direct group measurements extragalactic objects. The is found to be 3.00±0.03×108 ms-1 invariant, within experimental error, over range redshifts measured (0≤z≤1.33). This measurement provides additional validation general...
