The VLT MUSE NFM view of outflows and externally photoevaporating discs near the orion bar★
(Oxford University Press (OUP), 2023-09-01)We present Very Large Telescope/Multi-Unit Spectroscopic Explorer Narrow Field Mode observations of a pair of disc-bearing young stellar objects towards the Orion Bar: 203–504 and 203–506. Both of these discs are subject ... -
Photosynthesis Under a Red Sun: Predicting the absorption characteristics of an extraterrestrial light-harvesting antenna
(Oxford University Press (OUP), 2023)Here, we discuss the feasibility of photosynthesis on Earth-like rocky planets in close orbit around ultracool red dwarf stars. Stars of this type have very limited emission in the photosynthetically active region of the ... -
Measurement of the Bs0→ μμ effective lifetime with the ATLAS detector
(Springer Nature, 2023)This paper reports the first ATLAS measurement of the → μμ effective lifetime. The measurement is based on the data collected in... -
Search for dark matter produced in association with a Higgs boson decaying to tau leptons at s = 13 TeV with the ATLAS detector
(Springer Nature, 2023)A search for dark matter produced in association with a Higgs boson in final states with two hadronically decaying τ-leptons and missing transverse momentum is presented. The analysis uses 139 fb−1 of proton-proton collision ... -
A new approach and code for spinning black holes in modified gravity
(IOP Publishing Ltd, 2023)We discuss and implement a spectral method approach to computing stationary and axisymmetric black hole solutions and their properties in modified theories of gravity. The resulting code is written in the Julia language ... -
Multi-field inflation with large scalar fluctuations: non-Gaussianity and perturbativity
(IOP Publishing, 2023-09-01)Recently multi-field inflation models that can produce large scalar fluctuations on small scales have drawn a lot of attention, primarily because they could lead to primordial black hole production and generation of large ... -
Buoyancy response of a disc to an embedded planet: a cross-code comparison at high resolution
(Oxford University Press (OUP), 2023-09-11)In radiatively inefficient, laminar protoplanetary discs, embedded planets can excite a buoyancy response as gas gets deflected vertically near the planet. This results in vertical oscillations that drive a vortensity ... -
Solar wind parameters influencing magnetosheath jet formation: low and high IMF cone angle regimes
(American Geophysical Union, 2023)Magnetosheath jets are localized flows of enhanced dynamic pressure that are frequently observed downstream of the Earth's bow shock. They are significantly more likely to occur downstream of the quasi-parallel shock than ... -
Anomaly detection search for new resonances decaying into a Higgs boson and a generic new particle X in hadronic final states using s=13 TeV pp collisions with the ATLAS detector
(American Physical Society (APS), 2023-09-01)A search is presented for a heavy resonance Y decaying into a Standard Model Higgs boson H and a new particle X in a fully hadronic final state. The full Large Hadron Collider run 2 dataset of proton-proton ... -
Search for a new Z′ gauge boson in 4μ events with the ATLAS experiment
(Springer Nature, 2023-07-01)This paper presents a search for a new Z′ vector gauge boson with the ATLAS experiment at the Large Hadron Collider using pp collision data collected at s = 13 TeV, corresponding to an integrated luminosity of 139 fb −1. ... -
Observation of electroweak production of two jets and a Z-boson pair
(Nature Research, 2023-02)Electroweak symmetry breaking explains the origin of the masses of elementary particles through their interactions with the Higgs field. Besides the measurements of the Higgs boson properties, the study of the scattering ... -

Search for Majorana neutrinos in same-sign WW scattering events from pp collisions at s=13 TeV
(Springer Nature, 2023-09)A search for Majorana neutrinos in same-sign WW scattering events is presented. The analysis uses s√=13 TeV proton–proton collision data with an integrated luminosity of... . -
Shocklets and Short Large Amplitude Magnetic Structures (SLAMS) in the high Mach foreshock of Venus
(Wiley Open Access, 2023)Shocklets and short large-amplitude magnetic structures (SLAMS) are steepened magnetic fluctuations commonly found in Earth's upstream foreshock. Here we present Venus Express observations from the 26th of February 2009 ... -
Self-consistent modeling of the energetic storm particle event of 10 November 2012
(EDP Sciences, 2023)Context. It is thought that solar energetic ions associated with coronal and interplanetary shock waves are accelerated to high energies by the diffusive shock acceleration mechanism. For this mechanism to be efficient, ... -
