  1. ChIcAGO Chasing the Identification of ASCAGalactic Objects Gemma Anderson

  2. 2-10 keV log N - log S relation measured in the Galactic Plane Hands et al. (2004)

  3. Identification Process Sub-arc second localisation with Chandra Compact (Un-resolved) ASCA Sources http://objekty.astro.cz/galaxie/sondy/chandra/chandra.html Obtain optical spectra of counterpart Compare source position with existing optical and infrared surveys 2MASS, DSS, GLIMPSE Counterpart • - Soft X-rays from nearby star • - Hard X-rays from highly absorbed massive star • - AGN, HMXB -- Usually hard X-ray sources No Counterpart Source Identified Image deeply in the NIR (PANIC instrument on Magellan) Counterpart Image deeply in the optical (IMACS instrument on Magellan) -- Possible CV, CWB, X-ray binary, AGN, Massive star Counterpart No optical Counterpart -- Possible PSR, magnetar, AGN, PWN No Counterpart Obtain optical spectra (IMACS) Obtain infrared spectra (OSIRIS on SOAR) Deeper O/IR observations with larger telescopes, colour statistics, X-ray timing analysis No Counterpart Counterpart or Source Identified Requires Further follow-up statistically identified
