Abundance Stratification in Type Ia Supernovae -- VIII. The 03fg-like SN\,2012dn: a double-degenerate merger interpretation
Charles J. Aouad, Paolo A. Mazzali, Stephan Hachinger +1
A detailed study using abundance tomography of SN 2012dn, a peculiar Type Ia supernova, is presented. Despite exhibiting a normal peak luminosity, it retains early-phase super-Chan…
Abundance stratification in type Ia supernovae -- VII. The peculiar, C-rich iPTF16abc: highlighting diversity among luminous events
Charles J. Aouad, Paolo A. Mazzali, Chris Ashall +2
Observations of Type Ia supernovae (SNe\,Ia) reveal diversity, even within assumed subcategories. Here, the composition of the peculiar iPTF16abc (SN\,2016bln) is derived by modeli…
Abundance stratification in type Ia supernovae -- VI: the peculiar slow decliner SN\,1999aa
Charles J. Aouad, Paolo A. Mazzali, Stephan Hachinger +6
The abundance distribution in the ejecta of the peculiar slowly declining Type Ia supernova (SN\,Ia) SN\,1999aa is obtained by modelling a time series of optical spectra. Similar t…
The structure and characteristic scales of the HI gas in galactic disks
Sami Dib, Jonathan Braine, Maheswar Gopinathan +9
The spatial distribution of the HI gas in galaxies holds important clues on the physical processes that shape the structure and dynamics of the interstellar medium (ISM). In this w…
Beirut explosion: Energy yield from the fireball time evolution in the first 230 milliseconds
Charles Aouad, Wissam Chemissany, Paolo Mazzali +2
The evolution of the fireball resulting from the August 2020 Beirut explosion is traced using amateur footage taken during the first 230 after the detonation. 38 frames…
Coupling local to global star formation in spiral galaxies: the effect of differential rotation
Charles Aouad, Philip James, Igor Chilingarian
Star formation is one of the key factors that shapes galaxies. This process is relatively well understood from both simulations and observations on a small "local" scale of individ…
