Global 3D hydrodynamical simulations show that a turbulence-driven deflagration-to-detonation transition produces nearly identical peak spectra across diverse ignition densities and topologies in near-Chandrasekhar white dwarfs, matching SN 1999aa.
SN 2025ogs is a spectroscopically normal Type Ia supernova at z=2.05 whose luminosity distance and properties are consistent with low-z standards and current LambdaCDM constraints.
A simulation-based inference framework that jointly models type Ia supernovae brightness dependences, host galaxy evolution, and cosmology from photometric observations.
Heliospheric plasma lensing and ENA contamination bias local distance-ladder photometry, accounting for a realistic 3–8 % of the Hubble tension after anisotropy and calibration effects.
A dual-head PINN couples H(z) and fσ8(z) through the GR growth ODE; with SH0ES or H0dN priors, fσ8 is systematically suppressed relative to ΛCDM while Om(z) is non-flat.
Photometry-only classification of SNe Ia and Ibc reaches >=90% accuracy by fitting a semi-analytical decay model to light curves and using GMMs on the resulting parameter distributions to estimate mixing fractions without any labeled training data.
skysurvey provides a Python framework with Target, Survey, and DataSet classes plus modeldag to simulate transient sky observations, demonstrated on Type Ia supernovae populations and ZTF DR2 replication.
Extended misalignment for axion-like particles with constant-ω_ϕ pre-oscillation and dark radiation coupling yields data-driven constraints favoring negative ω_ϕ and f_ϕ in [80, 1.5×10^10] TeV but does not ease cosmological tensions.
Large sample of SN Ia hosts shows young mean progenitor age of 3.5 Gyr and only 1.5 Gyr evolution, leading to negligible cosmological bias of 0.007 mag.
ACT DR6 CMB lensing map gives σ8 = 0.819 ± 0.015 and H0 = 68.3 ± 1.1 km/s/Mpc, consistent with Planck ΛCDM but 1.7-2.1σ higher in S8 than KiDS, DES, and HSC galaxy surveys.
No kilonova detected from sub-solar GW candidate S251112cm, but coincident IIb supernova SN 2025adtq yields suggestive evidence for the superkilonova channel, though inconclusive after accounting for chance coincidence.
BayeSN analysis of ZTF Type Ia supernovae confirms a ~0.1 mag intrinsic environmental step in standardized brightness that is not explained by differences in dust extinction properties.
Re-expressing the Hubble tension via posterior-implied E(z) histories yields moderate mismatches (S_hist of 1.65 and 2.55) that correspond to only 1.1-2.1 sigma equivalents, below the usual 4.9 sigma scalar-H0 discrepancy.
Calibration uncertainties during supernova light-curve fitting cause roughly 50% degradation in dark energy figure of merit for Stage IV surveys, dominating over 13% degradation from model training errors and showing near-degeneracy with cosmology.
A coordinated Rubin-DESI supernova survey could distinguish dynamical dark energy from Lambda CDM at over 5 sigma in one year using 2300 spectroscopically confirmed SNe Ia at low redshift.
Bayesian evidence prefers a low-redshift supernova magnitude offset over dynamical dark energy when DES-5Y is combined with DESI BAO, but only under the assumption that Lambda CDM is correct.
Underdamped dark-energy oscillator fits to DESI+DESY5/Union3 give H0≈71–72 km/s/Mpc, cutting SH0ES tension to ~1.5σ at no Bayesian cost versus ΛCDM.
A prototype photonic ring resonator device was characterized in the upper H-band, with a quadratic model for suppressed-wavelength progression found to be more consistent with data than a linear model, though depth and FWHM trends remain unresolved.
Best-fit viscous quintessence to the SNe Ia Master Sample shows no DESI-like phantom transition; SNe alone do not indicate a change in dark-energy nature.
SKAO radio surveys can link redshifts to GW luminosity distances, enabling constraints on H(z) and H0 via HI intensity maps and galaxy surveys.
K-essence cosmology induces a redshift-dependent effective mass on gravitational waves, causing phase shifts that link scalar field dynamics to GW observables without changing wave speed or luminosity distance.
Long-term multi-band photometry of SN 2019vxm shows initial thick CSM interaction, photosphere decoupling at 80-100 days, long-lasting dust emission, and a possible outer CSM rebrightening, implying a massive progenitor with extreme pre-explosion mass loss.
Applying a swampland-motivated lower bound on the dark-energy potential slope to curved quintessence shifts the inferred spatial curvature Ωk from near zero to about +0.0025, a mild and not statistically significant preference for an open universe.
