LIV effects on the quantum stochastic motion in an acoustic FRW-geometry

M. A. Anacleto, C. H. G. Bessa, F. A. Brito +3

It is well known in the literature that vacuum fluctuations can induce a random motion of particles which is sometimes called quantum Brownian motion or quantum stochastic motion.…

Why do many early-type galaxies lack emission lines? I. Fossil clues

F. Herpich, G. Stasińska, A. Mateus +2

Early-type retired galaxies (RGs, i.e. galaxies which no longer form stars) can be divided into two classes: those with no emission lines, here dubbed lineless RGs, and those with…

The many faces of LINER-like galaxies: a WISE view

F. R. Herpich, A. Mateus, G. Stasińska +2

We use the SDSS and WISE surveys to investigate the real nature of galaxies defined as LINERs in the BPT diagram. After establishing a mid-infrared colour W2-W3 = 2.5 as the optima…

J-PAS: The Javalambre-Physics of the Accelerated Universe Astrophysical Survey

N. Benitez, R. Dupke, M. Moles +149

The Javalambre-Physics of the Accelerated Universe Astrophysical Survey (J-PAS) is a narrow band, very wide field Cosmological Survey to be carried out from the Javalambre Observat…

A comprehensive classification of galaxies in the SDSS: How to tell true from fake AGN?

R. Cid Fernandes, G. Stasinska, A. Mateus +1

We use the W_Ha versus [NII]/Ha (WHAN) diagram to provide a comprehensive emission-line classification of SDSS galaxies. This classification is able to cope with the large populati…

Alternative diagnostic diagrams and the "forgotten" population of weak line galaxies in the SDSS

R. Cid Fernandes, G. Stasinska, M. S. Schlickmann +5

A numerous population of weak line galaxies (WLGs) is often left out of statistical studies on emission line galaxies (ELGs) due to the absence of an adequate classification scheme…
