The polar mid-infrared (MIR) emission detected within tens to hundreds of parsecs in some active galactic nuclei (AGN) has been associated with dusty winds driven away by radiation pressure. The physical characterization of this extended polar emission remains uncertain. Here, we combine 10─21 μm JWST/Mid-InfRared Instrument (MIRI) imaging

Context. Fossil groups (FGs) are groups or clusters of galaxies with a single, massive, central galaxy dominating their luminosity distribution, and with a clear lack of L ∗ galaxies. The physical reason for the large magnitude gap (∆m 12) in these systems is still a matter for investigation. It could originate in an early formation of FGs

We present results from a dual narrowband imaging survey targeting the CL1604 supercluster at z = 0.9 using the Subaru Telescope. By combining the NB921 filter on Hyper Suprime-Cam and the NB1244 filter on SWIMS, we can detect redshifted Hα and Hβ emission lines from the supercluster. This unique technique allows us to measure both star formation

Context. Free-floating planetary-mass objects (FFPs) have been detected through direct imaging in several young, nearby star-forming regions. The properties of circumstellar disks around these objects may provide a valuable probe into their origin but are currently limited by the small sample sizes explored. Aims. We aim to perform a statistical

Gamma-ray bursts (GRBs), particularly those detected by wide-field instruments such as the Fermi/GBM, pose challenges for optical follow-up because of their large initial localization regions, leaving many GRBs without identified afterglows. The Gravitational-wave Optical Transient Observer (GOTO), with its wide field of view, dual-site coverage

The Deep Extragalactic VIsible Legacy Survey (DEVILS) is a deep, high-completeness multiwavelength survey based around spectroscopic observations using the Anglo-Australian Telescope's AAOmega spectrograph. The survey covers $\sim 4.5$ deg $^{2}$ over three extragalactic fields to Y $_{\mathrm{ AB}}< 21.2$ mag and probes sources at $0< z< 1.2$
