The Mauritius radio telescope and a study of selected super nova remnants associated with pulsars [PDF]

, 1997
The just completed Mauritius Radio Telescope, a 2km by 1km T shaped synthesis array designed to repeat the 6C survey but for the Southern hemisphere, is described. Full details of the instrument hardware, and the software designed to interpret the output

Are Radio Minihalos Confined by Cold Fronts in Galaxy Clusters? Minihalos and Large-scale Sloshing in A3444 and MS 1455.0+2232

The Astrophysical Journal
We present radio and X-ray studies of A3444 and MS1455.0+2232, two galaxy clusters with radio minihalos in their cool cores. A3444 is imaged using the Giant Metrewave Radio Telescope (GMRT) at 333, 607, and 1300 MHz and the Very Large Array at 1435 MHz ...

Galaxy clustering and dynamics from redshift surveys [PDF]

, 1990
The clustering and dynamical properties of the 368 galaxies in the redshift surveys of Metcalfe et al. (1989) and Parker et al. (1986) are investigated. These galaxies were selected from ten high galactic latitude fields complete to a magnitude limit of ...

Mid-infrared Colors Vary with Galactic Environment: Contrasting Star-forming Disks, Young Centers, and Quiescent Star-formation Deserts

The Astrophysical Journal
We present 50–100 pc-resolution JWST/MIRI and NIRCam measurements of mid-infrared (mid-IR) color variations in the diffuse interstellar medium (ISM) of 71 nearby star-forming galaxies from the PHANGS-JWST survey.

Identifying Transitions in Changing-look Active Galactic Nuclei in Light-curve Data with the Zwicky Transient Facility

The Astrophysical Journal
Changing-look active galactic nuclei (CL-AGN) are AGN that transition between Seyfert types, challenging AGN unification models. Most CL-AGN have been identified via repeat spectroscopy, making it difficult to determine the duration and magnitude of the ...

JWST Discovery of a Very Fast Biconical Outflow of Warm Molecular Gas in the Nearby Ultraluminous Infrared Galaxy F08572+3915 NW

The Astrophysical Journal
We present new James Webb Space Telescope (JWST) Mid-Infrared Instrument Medium-Resolution Spectrometer observations of the nearby ultraluminous infrared galaxy (ULIRG) F08572+3915 NW. These integral field spectroscopic (IFS) data reveal a kpc-scale warm-

New Constraints on the Evolution of the MH i−M⋆ Scaling Relation Combining CHILES and MIGHTEE-H i Data

The Astrophysical Journal
The improved sensitivity of interferometric facilities to the 21 cm line of atomic hydrogen (H i ) enables studies of its properties in galaxies beyond the local Universe.

Virgo Filaments. IV. Using WISE to Measure the Modification of Star-forming Disks in the Extended Regions Around the Virgo Cluster

The Astrophysical Journal
Recent theoretical work and targeted observational studies suggest that filaments are sites of galaxy preprocessing. The aim of the WISESize project is to directly probe galaxies over the full range of environments to quantify and characterize extrinsic ...
