A Galactic-scale extreme-precision radial velocity survey
Sukanya Chakrabarti, Jack Wagner, Robert J. de Rosa +8
We describe the first Galactic-scale extreme-precision radial velocity (EPRV) survey and outline our goals of measuring Galactic accelerations and deriving constraints on the dark…
Discovery of a multiphase OVI and OVII absorber in the circumgalactic/intergalactic transition region
J. Ahoranta, A. Finoguenov, M. Bonamente +4
The observational constraints on the baryon content of the WHIM rely almost entirely on FUV measurements. However, cosmological, hydrodynamical simulations predict strong correlati…
Hot WHIM counterparts of FUV OVI absorbers: Evidence in the line-of-sight towards quasar 3C 273
Jussi Ahoranta, Jukka Nevalainen, Nastasha Wijers +7
We explore the high spectral resolution X-ray data towards the quasar 3C273 to search for signals of hot ( K) X-ray-absorbing gas co-located with two established inte…
Discovery of Galactic OIV and OV X-ray absorption due to transition temperature gas in the PKS 2155-304 spectrum
J. Nevalainen, B. Wakker, J. Kaastra +4
FUV observations have revealed the transition temperature gas (TTG; ~ 5), located in the lower Galactic halo and in the High Velocity Clouds. However, the c…
