Multiple outflows and delayed ejections revealed by early imaging of novae
Elias Aydi, John D. Monnier, Antoine Mérand +39
Novae are thermonuclear eruptions on accreting white dwarfs in interacting binaries. Although most of the accreted envelope is expelled, the mechanism -- impulsive ejection, multip…
Spectroscopic study of the Quiescent Stages in between the 2006 and 2021 outbursts of RS Ophiuchi
Gesesew R. Habtie, Ramkrishna Das
This paper presents a comprehensive spectroscopic analysis of the quiescent stage of the recurrent nova RS Ophiuchi between its 2006 and 2021 outbursts. The spectra shows prominent…
AGN and Star-Formation Properties of Inside-out Assembled Galaxy Candidates at z<0.1
Dejene Zewdie, Mirjana Pović, Manuel Aravena +2
We study a sample of 48127 galaxies selected from the SDSS MPA-JHU catalogue, with and . Local galaxies in this stellar mass range…
The properties of inside-out assembled galaxies at
Dejene Zewdie, Mirjana Pović, Manuel Aravena +2
In this work, we study the properties of galaxies that are showing the inside-out assembly (which we call inside-out assembled galaxies; IOAGs), with the main aim to understand bet…
Accretion rate in AGN and X-ray-to-optical flux ratio at z 0.2
Asrate Gaulle, Mirjana Pović, Dejene Zewdie
We explored a sample of 545 local galaxies using data from the 3XMM-DR7 and SDSS-DR8 surveys. We carried out all analyses up to z\,\,0.2, and we studied the relation between…
Multiwavelength morphological study of active galaxies
Betelehem Bilata-Woldeyes, Mirjana Pović, Zeleke Beyoro-Amado +2
Studying the morphology of a large sample of active galaxies at different wavelengths and comparing it with active galactic nuclei (AGN) properties, such as black hole mass ($M_{BH…
