Higher-Mach-number self-similar shock solutions in failed supernovae are unstable and strengthen asymptotically above a critical neutrino mass-loss threshold, explaining greater ejection in red supergiants versus compact progenitors.
New JWST and Keck data on off-nuclear TDE 2025abcr show shifting emission-line velocities from a changing reprocessing layer and an IR power-law slope of -2.13 that is consistent with either reprocessing gas or a young stellar cluster of mass ~10^7.6 solar masses.
GW190814 is proposed to originate from a collapsar-disk fragment merging with the central black hole, potentially preceded by SN2019npv ~60 days earlier, yielding H0 = 70.5 (+9.2, -6.4) km/s/Mpc.
A new radiative-diffusion framework couples magnetar spin-down, shock propagation, and radiative transport to produce double-peaked, merged, or single-peaked light curves in engine-powered transients, demonstrated on LSQ14bdq.
SCAT DR1 delivers 1810 spectra of 1330 transients with classifications, fitted light curves, new redshifts for many host galaxies, and host properties as a testbed for photometric classification pipelines.
Fitting 80 SNe Ic-BL lightcurves with a magnetar-plus-Ni model reveals a universal ejecta-mass–spin-period anti-correlation linking SNe Ic-BL, SLSNe, and FBOTs to a common magnetar origin.
EP250827b/SN 2025wkm is a new X-ray flash–supernova whose long, soft X-ray burst and double-peaked, plateauing optical light curve are best explained by a magnetar central engine interacting with a low-mass circumstellar shell.
The authors derive and calibrate analytical criteria, using a hydrogen-oxygen toy model and Cloudy simulations, that classify X-ray absorption states in photoionized gas across Thomson-thin and moderate-thick regimes, including scattering and boundary effects.
Uniform analysis of 25 events shows SNe Ibn, SNe Icn, and FBOTs overlap in peak luminosity, rise/decline times, colors, and fitted CSM/ejecta parameters, supporting a shared dense-CSM interaction framework for most but not the most extreme FBOTs.
The Via Project is a planned five-year dual-hemisphere spectroscopic survey targeting over 2 million stars with 100 m/s RV stability and transient spectroscopy to r~24 using instruments on MMT and Magellan/Clay telescopes starting in 2027.
High luminosities above 10^44 erg/s and compact radii below 10^14 cm suppress H and He lines via high ionization and temperature, with non-homologous compact outflows needed for persistent featurelessness in LFBOTs and TDEs.
EP260321a is identified as the faintest shock breakout X-ray transient associated with broad-lined Ic supernova SN 2026gzf, interpreted as originating from a mildly relativistic weak outflow choked inside the progenitor star.
TESS and ZTF observations of 12 LFBOTs yield no late-time flares after SSO attribution, constraining central engine lifetimes to hundreds of days or less.
