We report on the measurement of the height-dependent time shifts of wave pulses in the lower solar atmosphere from high-resolution spectropolarimetric observations obtained with the SUSI instrument on board the SUNRISE III balloon-borne solar observatory during its successful science flight in 2024 July. The line-of-sight velocities derived from

We present the discovery and multiwavelength follow-up of gamma-ray bursts (GRB) 250818B, detected by the Space Variable Objects Monitor (SVOM) and localized by the Gravitational-wave Optical Transient Observer. We compile X-ray, optical/near-infrared, and radio data into broad-band light curves and spectral energy distributions. Despite being

This Letter presents JWST MIRI/Medium-Resolution Spectrometer (MRS) observations of the central r ≈ 40--240 pc regions of five active galactic nuclei (AGN) spanning a wide range of luminosities (log L bol/erg s -1 ≈ 39.8--43.8). Combining multiphase diagnostics from polycyclic aromatic hydrocarbons (PAHs), molecular hydrogen (H 2), and ionized gas

We present the first spatially resolved kinematic evidence for dust in the outflows of active galactic nuclei (AGNs). We utilize observations from James Webb Space Telescope with Near Infrared Spectrograph Integral Field Unit (NIRSpec IFU) and Mid-Infrared Instrument Medium Resolution Spectroscopy (MIRI MRS) data of 10 local Seyferts and use

The recently discovered low-ionisation broad absorption line (LoBAL) quasar GQ 1309+2904 is unusual due to its very broad, highly blueshifted absorption troughs and an absence of broad emission lines except for Hα. In this paper, we present observations of six quasars that appear very similar to GQ 1309+2904 in the rest-frame ultraviolet (UV). We

Context. Giant Low Surface Brightness galaxies (gLSBGs), such as Malin 1, host extended stellar and gaseous discs exceeding 100 kpc in radius. Their formation and evolution remain debated, with interactions with satellite galaxies and accretion streams proposed as key contributors. Malin 1 presents multiple nearby and distant satellites
