The coronal dynamics imagers for the KuaFu mission
Lamy, P.; Rousset, G.; Vives, S. +1 more
The Space Weather Explorer - KuaFu mission will provide simultaneous, long-term, and synoptic observations of the complete chain of disturbances from the solar atmosphere to the geospace. KuaFu-A (located at the L1 liberation point) includes Coronal Dynamics Imagers composed of a Lyman-α coronagraph (from 1.15 to 2.7 solar radii) and a white light…
Evolution of galaxy cluster scaling from XMM-Newton observation of the galaxy clusters at z ⩾ 0.4
Anokhin, S. G.
We present here new XMM-Newton observations of 3 relatively cool clusters at z ≈ 0.4, complemented by archival observations of 3 other clusters at similar redshift. We derived the M- T and R- T relations from the hydrostatic equation using an isothermal temperature distribution.
QSO number counts to B < 24.5 from hubble space telescope WFPC2 images
Anderson, Scott F.; Beck-Winchatz, Bernhard
We have conducted a survey for faint quasars to B < 24.5, z < 2.1 based on archival high-latitude Hubble Space Telescope Wide Field Planetary Camera 2 (WFPC2) images covering 0.04 deg2 of the sky in three filters spanning 2300 9600 Å. Taking advantage of the superb 0.1″ resolution of WFPC2, we have developed an approach to select …
Spectroscopic observations of coronal waves and coronal mass ejections
Harra, L. K.
It is common to use imaging instruments such as EUV and X-ray imagers and coronagraphs to study large-scale phenomena such as coronal mass ejections and coronal waves. Although high resolution spectroscopy is generally limited to a small field of view, its importance in understanding global phenomena should not be under-estimated. I will review cu…
High resolution X-ray spectroscopy and chemical evolution in elliptical galaxies
Loewenstein, Michael; Davis, David S.
We discuss the elemental composition in the hot ISM of elliptical galaxies derived from new and recent X-ray spectral analysis in the context of new phenomenological models of their chemical evolution. Star formation histories, the IMF, the astrophysics of supernovae, and the nature of galactic winds impact the metal content and relative abundance…
Possibility to detect the cluster emission up to R200 with XMM-Newton data
Sauvageot, J. -L.; Solovyeva, L.; Anokhin, S.
We present the results of analysis XMM-Newton data of galaxy cluster CL0016+16, which enables us to trace X-ray emission and temperature profile up to the virial radius. We obtained similar results using three different backgrounds. We checked the possibility of detection of cluster emission up to the virial radius with XMM-Newton data with hydrod…
