The International Pulsar Timing Array second data release: Search for an isotropic Gravitational Wave Background / Antoniadis, J. (FORTH, Heraklion ; Bonn, Max Planck Inst., Radioastron. ; Argelander Inst. Astron.) ; Arzoumanian, Z. (NASA, Goddard) ; Babak, S. (APC, Paris) ; Bailes, M. (Swinburne U. Tech., Hawthorn ; ARC, CoEPP, Australia) ; Nielsen, A.-S. Bak (Bonn, Max Planck Inst., Radioastron. ; Bielefeld U.) ; Baker, P.T. (Widener U.) ; Bassa, C.G. (ASTRON, Dwingeloo) ; Becsy, B. (Montana State U.) ; Berthereau, A. (LPC2E, Orleans ; Station Radioastronomy, Nancay) ; Bonetti, M. (Milan Bicocca U. ; INFN, Milan Bicocca) et al.
We searched for an isotropic stochastic gravitational wave background in the second data release of the International Pulsar Timing Array, a global collaboration synthesizing decadal-length pulsar-timing campaigns in North America, Europe, and Australia. In our reference search for a power law strain spectrum of the form $h_c = A(f/1\,\mathrm{yr}^{-1})^{\alpha}$, we found strong evidence for a spectrally-similar low-frequency stochastic process of amplitude $A = 3.8^{+6.3}_{-2.5}\times10^{-15}$ and spectral index $\alpha = -0.5 \pm 0.5$, where the uncertainties represent 95% credible regions, using information from the auto- and cross-correlation terms between the pulsars in the array.

The second data release from the European Pulsar Timing Array - IV. Implications for massive black holes, dark matter, and the early Universe / EPTA Collaboration
The European Pulsar Timing Array (EPTA) and Indian Pulsar Timing Array (InPTA) collaborations have measured a low-frequency common signal in the combination of their second and first data releases respectively, with the correlation properties of a gravitational wave background (GWB). Such signal may have its origin in a number of physical processes including a cosmic population of inspiralling supermassive black hole binaries (SMBHBs); inflation, phase transitions, cosmic strings and tensor mode generation by non-linear evolution of scalar perturbations in the early Universe; oscillations of the Galactic potential in the presence of ultra-light dark matter (ULDM).

The Hi-GAL compact source catalogue – I. The physical properties of the clumps in the inner Galaxy (−71$_{.}^{\circ}$0 < ℓ < 67$_{.}^{\circ}$0) / Elia, Davide (INAF, Rome) ; Molinari, S. (INAF, Rome) ; Schisano, E. (INAF, Rome) ; Pestalozzi, M. (INAF, Rome) ; Pezzuto, S. (INAF, Rome) ; Merello, M. (INAF, Rome) ; Noriega-Crespo, A. (Baltimore, Space Telescope Sci.) ; Moore, T.J. T. (Liverpool John Moores U., ARI) ; Russeil, D. (Marseille, Lab. Astrophys.) ; Mottram, J.C. (Heidelberg, Max Planck Inst. Astron.) et al.
Hi-GAL is a large-scale survey of the Galactic plane, performed with Herschel in five infrared continuum bands between 70 and 500 $\mu$m. We present a band-merged catalogue of spatially matched sources and their properties derived from fits to the spectral energy distributions (SEDs) and heliocentric distances, based on the photometric catalogs presented in Molinari et al.

Euclid preparation. Sensitivity to non-standard particle dark matter model / Euclid Collaboration
The Euclid mission of the European Space Agency will provide weak gravitational lensing and galaxy clustering surveys that can be used to constrain the standard cosmological model and its extensions, with an opportunity to test the properties of dark matter beyond the minimal cold dark matter paradigm.

Measurement of the Branching Ratio for the Process $b \to \tau^{-}\overline{\nu}_{\tau}X$ / OPAL Collaboration
The inclusive branching ratio for the process b -> tau nu X has been measured using hadronic Z decays collected by the OPAL experiment at LEP in the years 1992-2000. The result is: BR(b -> tau nu X) = (2.78 +/- 0.18 +/- 0.51)% This measurement is consistent with the Standard Model expectation and puts a constraint of tan(beta) / M(H+/-) < 0.53 GeV-1 at the 95% confidence level on Type II Two Higgs Doublet Models..

Search for Subsolar-Mass Binaries in the First Half of Advanced LIGO’s and Advanced Virgo’s Third Observing Run / LIGO Scientific Collaboration
We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2 $M_\odot$ and 1.0 $M_\odot$ in Advanced LIGO and Advanced Virgo data collected between 1 April 2019 1500 UTC and 1 October 2019 1500 UTC. We extend previous analyses in two main ways: we include data from the Virgo detector and we allow for more unequal mass systems, with mass ratio $q \geq 0.1$. [...]

Detection of the Schwarzschild precession in the orbit of the star S2 near the Galactic centre massive black hole / GRAVITY Collaboration
The star S2 orbiting the compact radio source Sgr A* is a precision probe of the gravitational field around the closest massive black hole (candidate). Over the last 2.7 decades we have monitored the star's radial velocity and motion on the sky, mainly with the SINFONI and NACO adaptive optics (AO) instruments on the ESO VLT, and since 2017, with the four-telescope interferometric beam combiner instrument GRAVITY.

Search for Radions at LEP2 / OPAL Collaboration
A new scalar resonance, called the radion, with couplings to fermions and bosons similar to those of the Higgs boson, is predicted in the framework of Randall-Sundrum models, proposed solutions to the hierarchy problem with one extra dimension. An important distinction between the radion and the Higgs boson is that the radion would couple directly to gluon pairs, and in particular its decay products would include a significant fraction of gluon jets.
