GASP XXXIX: MeerKAT hunts Jellyfish in A2626

نویسندگان

چکیده

We present MeerKAT HI observations of six jellyfish candidate galaxies (JFCGs) in the galaxy cluster, A2626. Two JW100 and JW103, that were identified as JFCGs from B-band images, are confirmed (JFGs). Both JFGs have low content, reside cluster core, move at very high velocities ($\sim$ 3$\sigma_{cl}$). The other JFCGs, non-jellyfish galaxies, rich, with morphologies revealing warps, asymmetries, possible tidal interactions. A2626 three GASP sample show these stripped but not yet quenched. detect HI, Halpha, CO tails similar extent 50 kpc) JW100. Comparing multi-phase velocity channels, we do any or emission northern section tail where Halpha is present, possibly due to prolonged interaction between gas ICM. also observe an anti-correlation CO, which hints efficient conversion H2 southern part tail. find both RPS HI-to-H2 significant depletion channels for atomic gas. more disc than

The Meerkat Multicomputer

Meerkat is a distributed memory multicomputer architecture that scales to hundreds of processors Meerkat uses a two dimensional passive backplane to connect nodes composed of processors memory and I O devices The interconnect is conceptually simple inexpensive to design and build has low latency and provides high bandwidth on long messages However it does not scale to thousands of processors do...

GasP model in Archsim

Archsim is an event-based behavioral simulator intended for architectural explorations of Fleet [?] structures. This document outlines a model framework that we built for Archsim. The framework follows the notation from [?]. Building blocks of the model map to GasP control circuits [?]. Consequently, we expect that it should not be too difficult to automate translation from a model to a schemat...

Detecting Hunts in Wildlife Documentaries

We propose a multi-level video event detection methodology and apply it to animal hunt detection in wildlife documentaries. The proposed multi-level approach has three levels. The rst level extracts color, texture, and motion features, and detects moving object blobs. The mid-level employs a neural network to verify whether the moving object blobs belong to animals. This level also generates sh...

Squaring the FIFO in GasP

This paper presents a method for designing a special type of asynchronous circuits, called Gasp circuits, and illustrates the method by a novel design of a low-latency, high-throughput FIFO, called a Square FIFO. The design method includes a graphical notation that permits the specification not only of circuit topology but also of the time separation between any two succeeding events. A Square ...
