We present the first near-infrared Hubble diagram for Type II-P supernovae (SNe), to further explore their value as distance indicators.We use a modified version of the standardized candle method, which relies on the ...

Using data of three well observed Type II plateau supernovae (SNe II-P), SNe 1987A, 1999em, and 2003hn, and two atmosphere models by Eastman et al. and Dessart & Hillier, we derive calibrations for bolometric corrections ...

El reciente surgimiento de telescopios astronómicos enormes abre nuevas posibilidades para estudios astrofísicos, con los correspondientes desafíos respecto al análisis masivo de datos. Tomando ventaja de estas nuevas ...

Since the first discovery of a broad-lined type Ic supernova (SN) with a long-duration gamma-ray burst (GRB) in 1998, fewer than fifty GRB-supernovae (SNe) have been discovered. The intermediate-luminosity Swift GRB 161219B ...

We show that when a procedure is made to remove the tension between a supernova Ia (SN Ia) data set and observations from BAO and CMB, there might be the case where the same SN Ia set built with two different light-curve ...

Futuras pesquisas observacionais com investimentos, telescópios e tecnologias nunca antes vistos, estão sendo propostas na tentativa de se desvendar os mistérios do Universo. Em nosso trabalho, fornecemos um panorama desse ...

In this paper we briefly comment on the observational status of the possible physical association between unidentified EGRET sources and supernova remnants (SNRs) in our Galaxy. We draw upon recent results presented in the ...

Supernova remnants are among the most valuable astrophysical laboratory to study numerous physical processes involved in their evolution and interaction with the surrounding interstellar medium. These objects are one of ...
