Stratification of the AGN-Driven multi-phase outflows in the dwarf Seyfert galaxy NGC 4395
Payel Nandi, Luis Colina, Rogemar A. Riffel +5
We present a multi-wavelength study of nuclear outflows in the nearby dwarf Seyfert galaxy NGC~4395, which hosts an intermediate-mass black hole. Using \textit{JWST}/NIRSpec and MI…
Simultaneous emission from dust and gas in the planetary debris orbiting a white dwarf
Laura K. Rogers, Christopher J. Manser, Amy Bonsor +11
There is increasing evidence for the presence and variability of circumstellar dust and gas around white dwarfs that are polluted with exoplanetary material, although the origin of…
Exploring the central region of NGC 1365 in the ultraviolet domain
Kshama Sara Kurian, C. S. Stalin, Dominika Wylezalek +6
Active galactic nuclei (AGN) feedback and its impact on their host galaxies are critical to our understanding of galaxy evolution. Here, we present a combined analysis of new high…
Seven white dwarfs with circumstellar gas discs II: Tracing the composition of exoplanetary building blocks
L. K. Rogers, A. Bonsor, S. Xu +8
This second paper presents an in-depth analysis of the composition of the planetary material that has been accreted onto seven white dwarfs with circumstellar dust and gas emission…
A comparative analysis of the active galactic nucleus and star formation characteristics of broad and narrow line Seyfert 1 galaxies
Kshama S. Kurian, C. S. Stalin, S. Rakshit +4
We report here our comparative analysis of active galactic nucleus (AGN) and star formation (SF) characteristics of a sample of narrow-line Seyfert 1 (NLS1) and broad-line Seyfert…
Seven white dwarfs with circumstellar gas discs I: white dwarf parameters and accreted planetary abundances
L. K. Rogers, A. Bonsor, S. Xu +9
Observations of planetary material polluting the atmospheres of white dwarfs are an important probe of the bulk composition of exoplanetary material. Medium- and high-resolution op…
