  1. COLD FRONTS IN X-RAY RELAXED GROUPS FABIO GASTALDELLO INAF-IASF MILANO UC IRVINE

  2. COLD FRONTS (see Simona’s Astrosiesta talk) AND DYNAMICAL STATE • COLD FRONTS IN THE RELAXED GROUP NGC 5044 • THE CLASS OF COLD FRONTS IN RELAXED GROUPS: ANOTHER EXAMPLE IN IC 1860 … OUTLINE / MOTIVATION

  3. COLD FRONTS IN CLUSTERS IN MERGING CLUSTERS IN RELAXED CLUSTERS Markevitch & Vikhlinin 07

  4. COLD FRONTS IN CLUSTERS Ascasibar & Markevitch 06

  5. COLD FRONTS IN CLUSTERS Markevitch & Vikhlinin 07

  6. HOW ABOUT GROUPS ? EXAMPLES IN MERGING SYSTEMS, e.g. NGC 1404 IN FORNAX (Machacek+05)

  7. COLD FRONTS IN NGC 5044 FIRST BRIEF MENTION OF A POSSIBLE COLD FRONT IN THE RELAXED GROUP NGC 5044 (BUOTE+02)

  8. COLD FRONTS IN NGC 5044 MENDEL+08 STUDY OF 111 MEMBERS: PECULIAR VELOCITY OF 150 km/s WRT THE MEAN VELOCITY

  9. COLD FRONTS IN NGC 5044 GASTALDELLO+08: arXiv0807.3526

  10. COLD FRONTS IN NGC 5044 280-350 350-80 GASTALDELLO+08: arXiv0807.3526

  11. COLD FRONTS IN NGC 5044 GASTALDELLO+08

  12. COLD FRONTS IN NGC 5044 GASTALDELLO+08

  13. COLD FRONTS IN NGC 5044 GASTALDELLO+08

  14. COLD FRONTS IN NGC 5044 DETECTION OF A SUBSTRUCTURE (99.9 %) AT 1.4 Mpc MENDEL+08

  15. IC 1860 ONE SOURCE MIGHT JUST BE ODD, TWO ARE A CLASS ~ 70 MEMBERS FROM 2DF, AGAIN PECULIAR VELOCITY OF THE cD w/ 140 km/s

  16. OK, BUT WHY DO WE CARE ? STEPS TOWARDS A PRECISE CHARACTERIZATION OF THE DYNAMICAL STATE OF A CLUSTER/GROUP THANKS TO MULTI-LAMBDA OBSERVATIONS Markevitch & Vikhlinin 07
