2024年1月5日 · It shows a nearby cluster of galaxies called Abell 2319, unveiling its detailed structure. In purple we see X-ray light measured by XRISM; this light is emitted by million-degree gas that permeates between the galaxies in the cluster.

2009年12月25日 · Abell 2319 (A 2319) is one of the most well-known examples of merging clusters with a giant radio halo. Two subgroups, A 2319A and A 2319B, are recognized in the radial-velocity distribution of the member galaxies, which suggests that the merger axis is nearly along the line-of-sight and that the velocity difference between them is almost 3000 ...

2024年1月17日 · JAXA’s XRISM mission provides a groundbreaking image of the Abell 2319 galaxy cluster, using X-ray and visible light to reveal its intricate structure and dynamics, enhancing our cosmic understanding. This pioneering, single-shot image is one of the first from JAXA’s XRISM mission.

1997年12月1日 · New radio and X-ray data are reported for the rich cluster Abell 2319. This object is known from optical data to consist of two separate clusters, which are displaced by about 10′ in the NW direction, and could be in a pre-merger state.

2020年11月23日 · We analysed the deep archival Chandra observations of the high-temperature galaxy cluster Abell 2319 to investigate the prominent cold front in its core. The main sharp arc of the front shows wiggles, or variations of the radius of the density jump along the arc.

This series of images shows Abell 2319, a nearby cluster of galaxies, in seven different frequency channels, from 44 to 545 GHz. The characteristic frequency dependence of the Sunyaev-Zel'dovich Effect is evident from a comparison of the various images.

Electron gas pressure profile derived from the density and temperature profiles. Entropy profile derived from density and temperature as K=Tne-2/3. The dashed line is the best-fit for the model K (r) = K0+K100(r/100 kpc)α with fit values: K0 = 270.23 ± 4.83 keV cm 2K100 = 39.42 ± 7.15 keV cm 2α = 1.76 ± 0.15.

2024年1月17日 · 日本宇宙航空研究开发机构的 XRISM 任务利用 X 射线和可见光揭示了 Abell 2319 星系集群的复杂结构和动态，提供了一幅突破性的图像，加深了我们对宇宙的了解。

2010年9月15日 · Abell 2319 lies around 800 million light years away and contains hundreds of galaxies of all shapes and sizes. An image of the cluster in visible light can be seen on the right. The centre of the cluster is marked by a cloud of gas, which is …

2024年3月1日 · Xtend successfully captured X-ray images of the galaxy cluster Abell 2319, situated approximately 770 million light-years away, during observations conducted from October 14-24, 2023.
