Topics  for  Discussion   •  Is  the  thick  gas  disk  (DIG,  HI  halos,  dust  halos)   the  “inner”  CGM?   •  What  is  the  structure  of  the  CGM?  Do  the  gas   kinema_cs  agree  with  simula_ons?

AGN  

Unexpected  BlueshiHed   Line  Wings  on  Lyα

•  AGN?   –  Dominate  LBol  in  two  systems   –  Rest  are  starburst  dominated  

•  Infall?   –  Unlikely  at  1000  –  2000  km/s   –  Would  places  the  gas  on  the   backside  of  the  dusty  ULIRG;   seems  unlikely.  

•  Bulk  mo(on  required;  not  just   sca5ering  in  frequency  space.   •  Low  column  density  N(HI)   –  Possible  along  the  UV  sightlines   –  High  velocity  because  it  is   condensing  out  of  the  hot  wind.

Gas  Inflows/OuPlows  in  the  Inner  Kpc   •  Infrared  isophotes  are  perpendicular  to  op_cal  isophotes.   •  Resolve  a  non-­‐axisymmetric,  circumnuclear  structure.   •  Size  R≈0.42”  (520  pc)  is  consistent  with  a    nuclear  disk.   Mar_n  &  Soto  2016  ApJ,  819,  49   Op(cal,Echellete   Spectroscopy

OuPlow  lobes  coincide  with  regions  of  low  reddening.   OuPlow  accelerates  150  km/s  over  1  kpc  (in  projec_on).   A  106  MO  cluster  might  provide  ample  Prad  (Murray+2011).   Note  the  absence  of  fast  ouPlow  in  the  nucleus!
