The evolution of the low-density HI intergalactic medium from z=3.6 to 0: Data, transmitted flux and HI column density
Tae-Sun Kim, Bart P. Wakker, Fahad Nasir +8
We present a new, uniform analysis of the HI transmitted flux (F) and HI column density (N(HI)) distribution in the low-density IGM as a function of redshift z for 0<z<3.6 using 55…
Spectroscopic Observations of the Fermi Bubbles
Andrew J. Fox, Trisha Ashley, Robert A. Benjamin +9
Two giant plasma lobes, known as the Fermi Bubbles, extend 10 kpc above and below the Galactic Center. Since their discovery in X-rays in 2003 (and in gamma-rays in 2010), the Bubb…
Probing Inhomogeneity in the Helium Ionizing UV Background
Sean Morrison, Matthew M. Pieri, David Syphers +1
We present an analysis combining the simultaneous measurement of intergalactic absorption by hydrogen (H I), helium (He II) and oxygen (O VI) in UV and optical quasar spectra. The…
Probing the Outflowing Multiphase Gas ~1 kpc Below the Galactic Center
Blair D. Savage, Tae-Sun Kim, Andrew J. Fox +8
Comparison of ISM absorption in the UV spectrum of LS 4825, a B1 Ib-II star d=21+/-5 kpc from the Sun toward l = 1.67 deg and b = -6.63 deg, with ISM absorption toward an aligned f…
The effect of stellar and AGN feedback on the low redshift Lyman- forest in the Sherwood simulation suite
Fahad Nasir, James S. Bolton, Matteo Viel +4
We study the effect of different feedback prescriptions on the properties of the low redshift () Ly forest using a selection of hydrodynamical simulations drawn from t…
The Lyman-alpha forest power spectrum from the XQ-100 Legacy Survey
Vid Iršič, Matteo Viel, Trystyn A. M. Berg +12
We present the Lyman- flux power spectrum measurements of the XQ-100 sample of quasar spectra obtained in the context of the European Southern Observatory Large Programme "Quasa…
