Sharpening quasar absorption lines with ESPRESSO: Temperature of warm gas at , constraints on the Mg isotopic ratio, and structure of cold gas at
P. Noterdaeme, S. Balashev, C. Ledoux +7
We present a high-resolution (R=140,000) spectrum of the bright quasar HE0001-2340 (z=2.26), obtained with ESPRESSO at the Very Large Telescope. We analyse three systems at z=0.45,…
Jeans smoothing of the Ly forest absorption lines
K. N. Telikova, S. A. Balashev, P. S. Shternin
We investigate a contribution of the Jeans smoothing to the minimal width of Ly forest lines and discuss how the accounting for this additional broadening affects the inferred p…
Thermal state of the intergalactic medium at
K. N. Telikova, P. S. Shternin, S. A. Balashev
We present a new method to infer parameters of the temperature-density relation in the intergalactic medium in the post-reionization epoch at . This method is based on t…
Stellar and dark matter density in the Local Universe
I. D. Karachentsev, K. N. Telikova
We calculate the mean density profiles for luminous and dark matter on distance scales Mpc around us using recent all-sky catalogs of galaxy groups. Within the Lo…
Estimation of the temperature-density relation in the intergalactic medium at via Ly forest
K N Telikova, S A Balashev, P S Shternin
Quasar spectra provide a unique opportunity to investigate the intergalactic medium at high redshifts. The spectral analysis of the Ly forest allows us to constrain the effectiv…
Equation of state of the intergalactic medium in the early Universe
K. N. Telikova, S. A. Balashev, P. S. Shternin
Spectroscopy of the Ly forest in quasar spectra proved to be a useful tool for probing the intergalactic gas. We developed the automatic program for Voigt profile fitting of Ly$…
