Abstract: We have investigated the ionic column density variability of the ionized outflows associated with NGC 7469, to estimate their location and power. This could allow a better understanding of galactic feedback of AGNs to their… read more here.

DOI: 10.1093/mnras/stx870
Abstract: Broad absorption lines (BALs) found in a significant fraction of quasar spectra identify highâvelocity outflows that might be present in all quasars and could be a major factor in feedback to galaxy evolution. Understanding the… read more here.

DOI: 10.5194/amt-12-2545-2019
Abstract: Abstract. We present a new numerical code, Mexican MAX-DOAS Fit (MMF), developed to retrieve profiles of different trace gases from the network of MAX-DOAS instruments operated in Mexico City. MMF uses differential slant column densities… read more here.
