Superdiscs in radio galaxies: jet–wind interactions [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 Taking a clue from their sharp-edged (strip-like) morphology observed in several cases, a new mechanism is proposed for the formation of the emission gaps seen between the radio lobes of many powerful extragalactic double radio sources. Canonical understanding of the radio gaps invokes either blocking of the back-flowing lobe plasma by the denser ...

Winds and infalling gas in Lyman break galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 A model for gas outflows is proposed which simultaneously explains the correlations between the (i) equivalent width of low ionization and Ly-alpha lines, (ii) outflow velocity, and (iii) star formation rate observed in Lyman Break Galaxies (LBGs).

DUST-DRIVEN WIND FROM DISK GALAXIES [PDF]
The Astrophysical Journal, 2011 We study gaseous outflows from disc galaxies driven by radiation pressure on dust grains. We include the effect of bulge and dark matter halo and show that the existence of such an outflow implies a maximum value of disc mass-to-light ratio. We show that the terminal wind speed is proportional to the disc rotation speed in the limit of a cold gaseous ...

On the Population of Wind-accreting Neutron Stars in the Galaxy
The Astrophysical Journal, 2002 We explore the possibility that neutron stars accreting from the winds of main-sequence stellar companions account for a significant fraction of low-luminosity, hard X-ray sources ...

A Candle in the Wind: A Radio Filament in the Core of the A3562 Galaxy Cluster [PDF]
The Astrophysical Journal, 2022 Abstract Using a MeerKAT observation of the galaxy cluster A3562 (a member of the Shapley supercluster), we have discovered a narrow, long and straight, very faint radio filament, which branches out at a straight angle from the tail of a radio galaxy located in projection near the core of the cluster. The radio filament spans 200 kpc and

The Astrophysical Journal, 1980 Since the neutral gas distribution in the disk exhibits a minimum from 0.5 to 4 kpc (in the bulge), we investigate whether a bulge wind is responsible for keeping this region gas-poor. Analytic methods are used to show that a wind must exist throughout most of the bulge, if current estimates of supernova heating rates and stellar mass-loss rates are ...

9.18. Galactic winds in active galaxies [PDF]
Symposium - International Astronomical Union, 1998 The effects of large-scale galactic winds in active galaxies may be far-reaching. It has been suggested that the Hubble sequence can be understood in terms of a galaxy's greater ability to sustain winds with increasing bulge-to-disk ratio. The large-scale circulation of gas associated with these galactic winds might help explain the mass-metallicity ...

Simulating supernova feedback in galaxy disks [PDF]
, 2012 In this thesis I examine supernova feedback in hydrodynamical simulations of galaxy disks. Understanding this process entails the numerical evaluation of cooling in radiative shocks, and we present a set of simulations using two widely used numerical ...

Surrogate‐Optimized Flow‐Guided Miniature Condenser for Rapid Exhaled Glucose Detection
Advanced Materials Technologies, EarlyView.A surrogate‐optimized miniature condenser guides humid exhaled flow toward cold surfaces to accelerate exhaled breath condensate collection. By improving vapor access within a compact footprint, the design increases sample yield. This enables post‐collection enrichment and rapid colorimetric glucose detection from dilute exhaled biomarkers within a 5 ...
