X-ray evolution of the nova V959 Mon suggests a delayed ejection and a non-radiative shock

Thomas Nelson, Koji Mukai, Laura Chomiuk +7

X-ray observations of shocked gas in novae can provide a useful probe of the dynamics of the ejecta. Here we report on X-ray observations of the nova V959 Mon, which was also detec…

Assessing the photometric redshift precision of the S-PLUS survey: the Stripe-82 as a test-case

A. Molino, M. V. Costa-Duarte, L. Sampedro +42

In this paper we present a thorough discussion about the photometric redshift (photo-z) performance of the Southern Photometric Local Universe Survey (S-PLUS). This survey combines…

SU Lyn: diagnosing the boundary layer with UV and hard X-ray data

Raimundo Lopes de Oliveira, Jennifer Sokoloski, Gerardo Juan Luna +2

Symbiotic stars in which the symbiotic phenomenon is powered solely by accretion, often at an average rate that is higher than in cataclysmic variable stars, provide an important o…

The origin of the puzzling hard X-ray emission of Cassiopeiae

Christian Motch, Raimundo Lopes de Oliveira, Myron A. Smith

Massive B and Be stars produce X-rays from shocks in high velocity winds with temperatures of a few million degrees and maximum X-ray luminosities of 10 erg/s. Sur…

The luminosity function of galaxies in elliptical-dominated galaxy groups: clues on the nature of fossil groups

Raimundo Lopes de Oliveira, Claudia Mendes de Oliveira, Renato Dupke +2

We have started a study of luminosity functions of Fossil Group candidates in order to characterize the faint-end of their galaxy distribution. Here we report on results of nine of…

On the X-ray and optical properties of the Be star HD 110432: a very hard-thermal X-ray emitter

Raimundo Lopes de Oliveira, Christian Motch, Myron A. Smith +3

(ABRIDGED) - HD 110432 is the first proposed, and best studied, member of a growing group of Be stars with X-ray properties similar to gamma Cas. These stars exhibit hard-thermal X…
