Gamma-ray bursts and supernovae: from the central engines to the observer

  A four-week scientific program on extreme explosive events (such as gamma-ray bursts, compact object mergers, core-collapse supernovae) is held at Institut d’Astrophysique Spatiale and sponsored by the Ψ2 initiative of the Paris-Saclay University. In this program we aim to bring together and foster interactions between several communities (core collapse supernovae, gamma-ray bursts, neutron star mergers and magnetars). For this […]

Gender stereotypes

The APC laboratory, one of UnivEarthS’ trustee, is committed to promoting and defending the place of women in science and particularly in physics. The persistence of gender stereotypes in professional careers was the subject of a discussion meeting organised by the Pôle égalité femmes hommes and the association Genera. A glimpse of these stereotypes that have a long life.

International symposium “50 Years of Plate Tectonics: Then, Now, and Beyond” on June 25-26, 2018

It took decades of research to accumulate the observations that led to the emergence of the theory of plate tectonics in the late 1960’s. Many contributions participated in its final acceptance — or “birth” — with seminal publications in (1) 1966 on the perfectly symmetrical distributions of magnetic anomalies on either side of the East-Pacific rise by Walter Pitman and […]

APC colloquium “Dark matter beyond WIMPs : light, warm, fuzzy and others” on Friday, June 15

  Eric Armengaud (IRFU/DPhP CEA Saclay) kindly accepted to give a colloquium entitled “Dark matter beyond WIMPs : light, warm, fuzzy and others”,at 11am on Friday, June 15, in room 454A of Condorcet building at Université Paris Diderot. Title: Dark matter beyond WIMPs : light, warm, fuzzy and others. Abstract: Many astrophysical and cosmological observations can only be interpreted assuming the existence of a dark matter component in […]
