Update of the European Strategy for Particle Physics
 
APPEC congratulates the CERN Council for its decision to update the European Strategy for Particle Physics setting up a vision for the future of particle physics, a process that was inclusive of the full Particle and Astroparticle Physics communities. The general considerations of the 2020 update acknowledge the importance of the rich and complementary physics programs of neighbouring fields. We look forward for the years to come and work together on the realization of these many synergies between Particle Physics and Astroparticle Physics to address the hiding secrets of fundamental physics laws in the tiny nooks of space and time.

New Chair and Vice-Chair for the APPEC Scientific Advisory Committee
 
During the last meeting of the General Assembly a new Chair and Vice-Chair for the Scientific Advisory Committee have been elected: Sijbrand de Jong takes over the duty as chair from Laura Baudis and Silvia Pascoli substitutes Jocelyn Monroe as Vice-Chair. We want to take this opportunity to thank Laura Baudis and Jocelyn Monroe for their successful work in the last two years and we wish the newly elected chairs all the best for their future tasks!

Gravitational Wave Probes of Fundamental Physics – a cross-cutting initiative
 
Interview on Gravitational Waves Expression of Interest with Tetyana Galatyuk and Paolo Pani: In response to the JENAS call the Gravitational Wave Community prepared an open Expression of Interest on “Gravitational Wave Probes of Fundamental Physics”. Already two weeks after the announcement, the list of endorses counted over 500 people. Tetyana Galatyuk and Paolo Pani, who played a key role in the writing and submission, will explain in this interview the aims and ideas of the EoI.

A new Science Vision and Infrastructure Roadmap for European Astronomy
 
Work is underway to develop a new, combined Science Vision and Infrastructure Roadmap, looking at the next 20 years of European astronomy, building upon the previous versions & updates delivered by Astronet (Science Vision, Infrastructure Roadmap). It is planned to publish this in early 2021. Astronet will be seeking input from the community and from associated areas, such as particle astrophysics, in the coming months.

Assembling the XENONnT Dark Matter Detector during Covid-19 Times
 
The nature of dark matter (DM), an invisible substance which constitutes 85% of matter in the observable universe, is one of the greatest puzzles in cosmology and astroparticle physics today. The XENON collaboration produced world-leading results in the hunt for dark matter with the XENON1T detector and was just beginning to assemble the upgrade, XENONnT, when Covid-19 hit the world. This article describes the remarkable work done by some members of the collaboration to build XENONnT during Covid-19 times.

Borexino performs the first detection ever of CNO cycle neutrinos from the Sun
 
At the recent Neutrino 2020 virtual meeting the Borexino Collaboration has announced the first detection ever of neutrinos from the CNO cycle in the Sun, an astounding experimental achievement, which closes a chapter of physics commenced in the years ‘30s of the past century.

Virgo and LIGO spot a mystery object merging with a black hole
 
Scientists from LIGO and Virgo have announced the discovery of an object of 2.6 solar masses, placing it firmly in the mass gap. About 800 million years ago, this object merged with a black hole and,  emitted an intense gravitational wave,  which was detected on Earth in August 2019.

CTA Prototype LST-1 Detects Very High-Energy Emission from the Crab Pulsar
 
Between January and February 2020 the LST-1 observed the Crab Pulsar, the neutron star at the centre of the Crab Nebula. The telescope, which is being commissioned on the CTA-North site on the island of La Palma and which just passed its Critical Design Review, was conducting engineering runs to verify the telescope performance and adjust operating parameters.

CUPID-Mo: a new world leading limit for neutrinoless double beta decay of 100Mo
 
The CUPID-Mo experiment is a demonstrator for CUPID, the next-generation upgrade of the first ton-scale cryogenic 0νββ-search, CUORE.
At the recent Neutrino2020 virtual conference, the Collaboration has presented a new world-leading limit for 0νββ decay of 100Mo, one of the most promising isotopes for this search .

Observation of Excess Events in the XENON1T Dark Matter Experiment
 
Scientists from the international XENON collaboration announced that data from XENON1T show a surprising excess of events.  The signature of the excess is similar to what might result from a tiny residual amount of tritium, but could also be a sign of something more exciting.

Fluorescent bicolour sensor for low-background neutrinoless double β decay experiments
This article is dedicated to the development of a bi-colour sensor for low-background neutrinoless double β decay experiments. It demonstrate an important step towards a ‘barium-tagging’ experiment, which identifies double β decay through the detection of a single Ba2+ ion. This has been develop to improve sensitivity of the NEXT experiment.
 
Resolving acceleration to very high energies along the jet of
Centaurus A
The H.E.S.S. collaboration published a breakthrough result in the magazine Nature, revealing the gamma-ray emission from the famous radio galaxy Centaurus A (also known as NGC 5128) to be spatially extended over thousands of light-years. This is the first time that an extragalactic source has been spatially resolved in the regime of very high energy gamma-ray astronomy and permits a direct determination of the size the region responsible for gamma-ray emission at TeV energies in an active galaxy.
