The Importance of Gas Starvation in Driving Satellite Quenching in Galaxy Groups at z ~ 0.8
The Astrophysical JournalWe present results from a Keck/DEIMOS survey to study satellite quenching in group environments at z ~ 0.8 within the Extended Groth Strip (EGS). We target 11 groups in the EGS with extended X-ray emission. We obtain high-quality spectroscopic redshifts

The Galaxy Density Environment of Gamma‐Ray Burst Host Galaxies
The Astrophysical Journal, 2004 We analyze cross-correlation functions between Gamma-Ray Burst (GRB) hosts and surrounding galaxies. We have used data obtained with the Very Large Telescope at Cerro Paranal (Chile), as well as public Hubble Space Telescope data. Our results indicate that Gamma-Ray Burst host galaxies do not reside in high galaxy density environments.

The Environments of Markarian Galaxies [PDF]
International Astronomical Union Colloquium, 1990 The extensively studied Markarian sample of 1500 ultraviolet excess galaxies contains many Seyfert, starburst, and peculiar galaxies. Using the 20 minute V plates obtained for the construction of the Hubble Space Telescope Guide Star Catalog, we have investigated the morphologies of the Markarian galaxies and the environments in which they are located.

Asking the 5 W's for designing next‐generation bioprocessing
AIChE Journal, EarlyView.Abstract Biotechnology is expanding beyond traditional, centralized fermentation and toward next‐generation bioprocessing paradigms that emphasize flexible deployment outside the laboratory with application‐specific performance. However, many bioprocesses fail to translate beyond proof‐of‐concept into industrially viable systems because early design ...

Why Are Some Optically Red Spirals Near-ultraviolet− r Blue?
The Astrophysical JournalTo understand the complicated formation processes of disk galaxies, we carry out a comparative study of near-ultraviolet (NUV)− r blue and red spiral galaxies drawn from a parent sample of u−r red spirals with M _* > 10 ^10.5 M _⊙ at 0.02

The Environments of Radio Galaxies [PDF]
Symposium - International Astronomical Union, 1996 In the unified schemes of AGNs BL Lac objects are believed to be Fanaroff-Riley (FR) type I radio galaxies with a relativistic jet aligned to the observer's line of sight (e.g. Urry & Padovani 1995). Kollgaard et al. (1992) and Owen et al. (1995) suggest some FR II sources can also be BL Lac parents. Clearly, isotropic properties such as the galaxy

Advanced Intelligent Systems, EarlyView.A low‐cost, portable point‐of‐care platform for rapid Mpox detection using loop‐mediated isothermal amplification is reported. The device integrates fluorescence readout and mobile monitoring. A machine‐learning model analyzes temperature data and correlates thermal changes with DNA concentration, enabling sensitive and reliable molecular diagnosis in ...

The SAGA Survey. VI. The Size–Mass Relation for Low-mass Galaxies Across Environments
The Astrophysical JournalWe investigate how Milky Way (MW)–like environments influence the sizes and structural properties of low-mass galaxies by comparing satellites of MW analogs from the Satellites Around Galactic Analogs (SAGA) Survey with two control samples: an ...

The Apparently Normal Galaxy Hosts for Two Luminous Quasars
, 1995 HST images (with WFPC2) of PHL~909\ ($z = 0.171$) and PG~0052$+$251\ ($z = 0.155$) show that these luminous radio-quiet quasars each occur in an apparently normal host galaxy. The host galaxy of PHL~909 is an elliptical galaxy ($\sim$ E4) and the host of

The THESEUS Space Mission and the Infrared Telescope Calibration Unit
Astronomische Nachrichten, EarlyView.ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an
