  • The Bright γ-ray Flare of 3C 279 in 2015 June: AGILE Detection and Multifrequency Follow-up Observations
    We report the AGILE detection and the results of the multifrequency follow-up observations of a bright γ-ray flare of the blazar 3C 279 in 2015 June. We use AGILE and Fermi gamma-ray data, together with Swift X-ray andoptical-ultraviolet data, and ground-based GASP-WEBT optical observations, including polarization information, to study the source

  • The binary fraction of planetary nebula central stars - III. the promise of VPHAS+
    The majority of planetary nebulae (PNe) are not spherical, and current single-star models cannot adequately explain all the morphologies we observe. This has led to the Binary Hypothesis, which states that PNe are preferentially formed by binary systems. This hypothesis can be corroborated or disproved by comparing the estimated binary fraction of

  • Suppression of Excited ϒ States Relative to the Ground State in Pb-Pb Collisions at √{s} NN=5.02 TeV
    The relative yields of ϒ mesons produced in p p and Pb-Pb collisions at √{sNN }=5.02 TeV and reconstructed via the dimuon decay channel are measured using data collected by the CMS experiment. Double ratios are formed by comparing the yields of the excited states, ϒ (2 S ) and ϒ (3 S ), to the ground state, ϒ (1 S ), in both Pb-Pb and p p

  • SNhunt151: an explosive event inside a dense cocoon
    SNhunt151 was initially classified as a supernova (SN) impostor (nonterminal outburst of a massive star). It exhibited a slow increase in luminosity, lasting about 450 d, followed by a major brightening that reaches MV ≈ -18 mag. No source is detected to MV ≳ -13 mag in archival images at the position of SNhunt151 before the slow rise. Low-to-mid

  • Seismic probing of the first dredge-up event through the eccentric red-giant and red-giant spectroscopic binary KIC 9163796. How different are red-giant stars with a mass ratio of 1.015?
    Context. Binaries in double-lined spectroscopic systems (SB2) provide a homogeneous set of stars. Differences of parameters, such as age or initial conditions, which otherwise would have strong impact on the stellar evolution, can be neglected. The observed differences are determined by the difference in stellar mass between the two components. The

  • Search for vectorlike light-flavor quark partners in proton-proton collisions at √{s }=8 TeV
    A search is presented for heavy vectorlike quarks (VLQs) that couple only to light quarks in proton-proton collisions at √{s }=8 TeV at the LHC. The data were collected by the CMS experiment during 2012 and correspond to an integrated luminosity of 19.7 fb-1 . Both single and pair production of VLQs are considered. The single-production search is
