Atmospheric Gas Motions in the Hydra A Galaxy Cluster
FY 2024-25 · 2025-03-24
Summary
Hydra A is the most powerful FR I radio source in the nearby Universe. Emanating from the central galaxy in a bright X-ray cluster, its jets have inflated a system of X-ray cavities and a surrounding Mach 1.3 shock front extending several hundred kiloparsecs into the cluster atmosphere. Its proximity (z=0.054) and large angular size requires two pointings to measure the energetics of the active inner jets and a second pointing toward the enormously powerful northern cavity and surrounding shock front. The pointings will reveal the expansion speed and cluster weather due to atmospheric bulk motion on the structure of the X-ray cavities. This measurement addresses the fundamental problem of how jet energy heats cluster atmospheres and prevents catastrophic cooling.

Description
Hydra A is the most powerful FR I radio source in the nearby Universe. Emanating from the central galaxy in a bright X-ray cluster, its jets have inflated a system of X-ray cavities and a surrounding Mach 1.3 shock front extending several hundred kiloparsecs into the cluster atmosphere. Its proximity (z=0.054) and large angular size requires two pointings to measure the energetics of the active inner jets and a second pointing toward the enormously powerful northern cavity and surrounding shock front. The pointings will reveal the expansion speed and cluster weather due to atmospheric bulk motion on the structure of the X-ray cavities. This measurement addresses the fundamental problem of how jet energy heats cluster atmospheres and prevents catastrophic cooling.
Description (French)
Hydra A est la source radio de type FR I la plus puissante dans l’Univers proche. Émanant de la galaxie centrale d’un amas brillant en rayons X, ses jets ont créés un système de cavités en rayons X et un front de choc environnant de Mach 1.3, s’étendant sur plusieurs centaines de kiloparsecs dans l’atmosphère de l’amas. Ces observations révéleront la vitesse d’expansion et les mouvements atmosphériques de l’amas, influencés par les mouvements massifs de l’atmosphère, sur la structure des cavités en rayons X. Cette étude permet d'étudier le problème fondamental de la manière dont l’énergie des jets chauffe les atmosphères des amas et empêche un refroidissement catastrophique.
Expected Results
