    I-V, C-V and deep level transient spectroscopy study of 24 MeV proton-irradiated bipolar junction transistor

    This paper describes the effect of 24 MeV proton irradiation on the electrical characteristics of a pnp bipolar junction transistor 2N 2905A. I-V, C-V and DLTS measurements are carried out to characterize the tra...

    Confined dense circumstellar material surrounding a regular type II supernova

    With the advent of new wide-field, high-cadence optical transient surveys, our understanding of the diversity of core-collapse supernovae has grown tremendously in the last decade. However, the pre-supernova e...

    A UV resonance line echo from a shell around a hydrogen-poor superluminous supernova

    Hydrogen-poor superluminous supernovae (SLSN-I) are a class of rare and energetic explosions that have been discovered in untargeted transient surveys in the past decade1,2. The progenitor stars and the physical ...

    Optical follow-up of the neutron star–black hole mergers S200105ae and S200115j

    LIGO and Virgo’s third observing run revealed the first neutron star–black hole (NSBH) merger candidates in gravitational waves. These events are predicted to synthesize r-process elements1,2 creating optical/nea...

    Discovery and confirmation of the shortest gamma-ray burst from a collapsar

    Gamma-ray bursts (GRBs) are among the brightest and most energetic events in the Universe. The duration and hardness distribution of GRBs has two clusters1, now understood to reflect (at least) two different prog...
