1. SN1014J in M82 A Pseudo-GOTOQ and what we can learn with really big telescopes and DIBs about QSOALS Donald G. York, Dan Welty, Jiaqi Jiang University of Chicago Julie Dahlstrom Carthage College Adam Ritchey University of Washington Galaxies in Absorption Paris, IAP, Sept. 22-24, 2014

2. SN2014A in M82

4. M82 General: Systemic velocity 209 km/sec At SNe: 133 km/sec (1 kpc from center) Starburst, dwarf (10 10 solar masses) Strong interaction with M81 0.3-1 Gyr. ago Central SFR, <10 Myr Outer parts >100 Myr Interstellar: H alpha filaments (reflection, but origin of dust??) Probably UV bump (not SMC/Calzetti) Where are filaments, where is SN (behind disk)? Mixed IS cloud properties High gamma ray flux (cosmic rays), high Li abundance

21. Velocity of Na I components (green) and positions of mean wavelength center of SN2014A DIBs

22. Models of DIB profiles based on a)Components derived from K I b)Assuming a weighting of 1:1 for 5780 to K I (red) c)Assuming a 1/1 weighting in the right components and 7/1 in the left (dense) components (green). d) Original data in black

23. Conclusions H I and 5780 correlation holds over several galaxies. K I and 4963 correlation likewise holds There are no dramatic differences in dust DIB relationships if radiation field is taken out using K I. DIBs of all sorts exist in M82: broad, narrow, C 2 and normal. There are a few features that might make M82 peculiar and might indicate similar conditions in GOTOs: CH+/CN and DIB ratios like DIB 6376/ 6379. Others are being explored.
