abstract
The Swift Gamma-Ray Explorer is designed to make prompt multiwavelength observations of Gamma-Ray Bursts (GRBs) and GRB afterglows. The X-ray Telescope (XRT) enables Swift to determine GRB positions with a few arcseconds accuracy within 100 seconds of the burst onset. The XRT utilizes a mirror set built for JET-X and an XMM/EPIC MOS CCD detector to provide a sensitive broad-band (0.2-10 keV) X-ray imager with effective area of > 120 cm^2 at 1.5 keV, field of view of 23.6 x 23.6 arcminutes, and angular resolution of 18 arcseconds (HPD). The detection sensitivity is 2x10^-14 erg cm^-2 s^-1 in 10^4 seconds. The instrument is designed to provide automated source detection and position reporting within 5 seconds of target acquisition. It can also measure the redshifts of GRBs with Fe line emission or other spectral features. The XRT operates in an auto-exposure mode, adjusting the CCD readout mode automatically to optimize the science return for each frame as the source intensity fades. The XRT will measure spectra and lightcurves of the GRB afterglow beginning about a minute after the burst and will follow each burst for days or weeks.

J1105+1452 transitioned to a megahertz peaked-spectrum source with a new compact jet of radius ~0.68 pc, apparent velocity ~0.64c, and Doppler factor ~12, while X-ray emission stayed disk-corona dominated.
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.
Six years of UV/X-ray monitoring of ESO 511-G030 reveals a >10x UV rise from the accretion disk, tight disk-corona coupling above ~1% Eddington, and breakdown below, indicating an accretion-state transition.
The earliest 1.3 mm observations of GRB 260127A detect 6.9 mJy emission 12.6 minutes post-trigger with a later non-detection implying decline at least as fast as t^{-0.5}, consistent with forward or reverse shock scenarios.
XSNAP provides a unified pipeline for X-ray supernova analysis and derives a progenitor mass-loss rate of (6.2±0.2)×10^{-5} solar masses per year for SN 2024ggi assuming a 20 km/s wind.
SAPLE is a new semi-automated pipeline for extracting Swift UVOT and XRT lightcurves, magnitudes, absorption-corrected fluxes, and photon index values assuming a redshifted power-law spectrum.
JWST observations of ERQs show stratified gas kinematics via deblended optical emission lines, with UV lines dominated by scattered light and optical lines mixing scattered and obscured emission.
A second coherent radio burst spanning 704-4032 MHz with spectral index -2.18, 54% linear and 22% circular polarization, and an orthogonal polarization angle jump was detected from 2XMM J104608.7-594306, showing rare radio activity in sources thought to be radio-quiet.
GRB 210704A at z=2.34 shows a luminous fast blue transient excess peaking at ~7 days, modeled as refreshed shock emission and linked to LFBOTs alongside a high-Lorentz-factor jet.
Multi-wavelength monitoring of nearby SNe Ic-BL adds new constraints on the fraction with relativistic jets comparable to SN 1998bw and flags candidates for choked jets and CSM-driven radio emission.

EP J174942.2-384834 is classified as a very faint X-ray transient black hole candidate based on its hard X-ray spectra, optical/UV brightening correlated with X-rays, and lack of radio emission.
2MASX J0413-0050 transitioned from a narrow-line Seyfert 1 to a Seyfert 1.9 and back while remaining in a high accretion state, supporting classification as a changing-state AGN.
HST-resolved SEDs for seven nearby BAT AGN show host-galaxy contamination biases accretion-disk temperature by ~2 eV, extinction by ~2.2 mag, bolometric luminosity by ~0.57 dex, and X-ray bolometric corrections by ~0.66 dex relative to Swift/UVOT data.
The 2026 outburst of 1A 1118-61 is brighter and spectrally harder than in 2009, with constant cyclotron line energy across large luminosity changes and QPO frequency suggesting magnetospheric instabilities.

Baselines of 8-11 ms light travel time for two CE detectors provide a reasonable compromise for BBH sky localization, with third detectors eliminating multimodality for most or all events.
