Catalog of magnetic white dwarfs with hydrogen dominated atmospheres

Autor: Amorim, L. L., Kepler, S. O., Külebi, Baybars, Jordan, S., Romero, A. D.

White dwarfs are excellent research laboratories as they reach temperatures, pressures, and magnetic fields that are unattainable on Earth. To better understand how these three physical parameters interact with each other and with other stellar featu

Diffuse ionized gas and its effects on nebular metallicity estimates of star-forming galaxies

Autor: Asari, N. Vale, Couto, G. S., Fernandes, R. Cid, Stasińska, G., de Amorim, A. L., Ruschel-Dutra, D., Werle, A., Florido, T. Z.

We investigate the impact of the diffuse ionized gas (DIG) on abundance determinations in star-forming (SF) galaxies. The DIG is characterised using the H$\alpha$ equivalent width ($W_{\text{H}\alpha}$). From a set of 1,409 SF galaxies from the Mappi
