Probing Dust Composition in Distant Galaxies with JWST Mid-IR Spectroscopy of Quasars with Foreground 2175 Å Absorbers II. Measurements of Grain Composition and Extinction Properties
Viacheslav V. Klimenko, Varsha P. Kulkarni, Monique C. Aller
We present results from a mini-survey of dust spectral features arising in galaxies at redshifts in our James Webb Space Telescope (JWST) mid-infrared spectra of ph…
Probing Dust Composition in Distant Galaxies with JWST Mid-IR Spectroscopy of Quasars with Foreground 2175 A Absorbers I: Methodology
Viacheslav V. Klimenko, Varsha P. Kulkarni, Monique C. Aller
Interstellar dust plays a crucial role in gas cooling and molecule formation, influencing galaxy evolution. However, the composition and structure of dust in distant galaxies are s…
Characterising the Circum-Galactic Medium of Damped Lyman- Absorbing Galaxies
Ramona Augustin, Celine Peroux, Palle Moller +8
Gas flows in and out of galaxies through their circumgalactic medium (CGM) are poorly constrained and direct observations of this faint, diffuse medium remain challenging. We use a…
Probing the Interstellar Dust in Galaxies over > 10 Gyr of Cosmic History
Varsha P. Kulkarni, Monique C. Aller, Donald G. York +3
This article is based on an invited talk given by V. P. Kulkarni at the 8th Cosmic Dust meeting. Dust has a profound effect on the physics and chemistry of the interstellar gas in…
Hubble Space Telescope Observations of Sub-Damped Lyman-alpha Absorbers at z < 0.5, and Implications for Galaxy Chemical Evolution
Debopam Som, Varsha P. Kulkarni, Joseph Meiring +5
We report observations of four sub-damped Lyman-alpha (sub-DLA) quasar absorbers at z<0.5 obtained with the Hubble Space Telescope Cosmic Origins Spectrograph. We measure the avail…
Probing Interstellar Silicate Dust Grain Properties in Quasar Absorption Systems at Redshifts z<1.4
Monique C. Aller, Varsha P. Kulkarni, Donald G. York +3
Absorption lines in the spectra of distant quasars whose sightlines pass through foreground galaxies provide a valuable tool to probe the dust and gas compositions of the interstel…
