Unprocessed RAW data is a highly valuable image format for image editing and computer vision. However, since the file size of RAW data is huge, most users can only get access to processed and compressed sRGB images. To bridge this gap, we design an Invertible Image Signal Processing (InvISP) pipeline, which not only enables rendering visually appealing sRGB images but also allows recovering nearly perfect RAW data. Due to our framework's inherent reversibility, we can reconstruct realistic RAW data instead of synthesizing RAW data from sRGB images without any memory overhead. We also integrate a differentiable JPEG compression simulator that empowers our framework to reconstruct RAW data from JPEG images. Extensive quantitative and qualitative experiments on two DSLR demonstrate that our method obtains much higher quality in both rendered sRGB images and reconstructed RAW data than alternative methods.

First detection of ultra-fast outflows in a quiescent galaxy
First detection of an ultra-fast outflow (v≈0.07c) in a quiescent galaxy quenched ~9 Gyr ago, suggesting AGN winds can maintain quiescence independent of global star formation.

Woven by the Whirls: The growth and entrainment of cold clouds in turbulent hot winds
Subsonic turbulence in a hot wind enlarges the cloud–wind mixing surface, boosting cold-cloud mass growth up to ~10× when cooling is fast and shortening entrainment time.

PhotoIFU: NIRCam as a Photometric Integral Field Unit for Mapping Feedback in Galaxies
PhotoIFU maps stellar mass, star-formation rate, dust, and metallicity pixel-by-pixel from JWST imaging, and finds gas-outflow regions are distinct from host galaxies in three z≈1.3–3.7 systems.

Direct Evidence for Outflow Driven by Wolf-Rayet Stars in the Nearby Galaxy PGC44685
MEGARA IFU data show a WR-driven [O III] outflow of mass ~8e3 Msun and rate ~9e-4 Msun/yr in PGC 44685, with only ~0.35% energy-loading efficiency on ~120 pc scales.

Stellar feedback drives the baryon deficiency in low-mass galaxies
Cool galactic outflows seen in stacked DESI spectra can escape low-mass galaxy halos, providing indirect evidence that stellar feedback drives their baryon deficiency.

Electron temperature relations in low metallicity, diffuse, and extraplanar gas of starburst galaxies
Te-Te relations from five auroral lines in four low-metallicity starbursts, including diffuse extraplanar gas, are consistent with spiral H II region relations, with one flagged exception.

The Nature of Post-Starburst Galaxies: Real Deal or Masquerading Impostors?
Most photometrically selected post-starburst galaxies in the FIREbox simulation are star-forming impostors, implying that AGN feedback is required to explain a long-lived quenched post-starburst population.

Impact of Cosmic Ray-driven Outflows on Lyman-$\alpha$ Emission in Cosmological Simulations
CR-driven outflows lower neutral hydrogen columns near young stars, boosting Ly-alpha escape, but only some observables (valley flux, surface brightness) distinguish CR from non-CR models.

JWST Discovery of Warm Dust in the Circumgalactic Medium of the Makani Galaxy
JWST detects PAH emission from warm dust extending to about 35 kpc in the Makani galaxy's wind, indicating starburst-ejected dust survives into the circumgalactic medium but is progressively eroded.

Superdiffusion of cosmic rays in the vicinity of their accelerators and the resulting $\gamma$-ray emission
Superdiffusion produces constant or r^{α-3} CR radial profiles near sources; the associated γ-ray morphology can distinguish it from normal diffusion with IACTs.

Dissecting the multiple-component outflow in NGC 5548 with absorption-line Variability
Absorption-line variability in NGC 5548 places four UV outflow components within about 3 pc of the black hole and two components at 36-44 pc.

Magnetogenesis by galactic processes: impact on circumgalactic and intergalactic fields
Halo magnetic fields at z=0 converge across primordial and astrophysical seeds via dynamo action, but IGM magnetization and coherence lengths retain seed memory and SN-only injection underproduces γ-ray lower limits.

New integral-field spectroscopy of quasar 3C 297 reveals an 18 kpc ionized gas outflow and jet-aligned young stars, interpreted as jet-dominated feedback in a merging host.
