Gravity coupled to a scalar field from a Chern-Simons action: describing rotating hairy black holes and solitons with gauge fields

Marcela Cárdenas, Oscar Fuentealba, Cristián Martínez +1

Einstein gravity minimally coupled to a scalar field with a two-parameter Higgs-like self-interaction in three spacetime dimensions is recast in terms of a Chern-Simons form for th…

Experimental analysis of heat and mass transfer in non-isothermal sloshing using a model-based inverse method

Pedro Marques, Alessia Simonini, Laura Peveroni +1

Nonisothermal liquid sloshing in partially filled reservoirs can significantly enhance heat and mass transfer between liquid and ullage gasses. This can result in large temperature…

Edge separators for graphs excluding a minor

Gwenaël Joret, William Lochet, Michał T. Seweryn

We prove that every $n$ -vertex $K_{t}$ -minor-free graph $G$ of maximum degree $Δ$ has a set $F$ of $O (t^{2} (lo g t)^{1/4} Δ n)$ edges such that every component of $G - F$ has at m…

Landau-Levich Enhanced Cheerios Effect

Hadrien Bense, Emmanuel Siéfert, Fabian Brau

We study the capillary attraction force between two fibers dynamically withdrawn from a bath. We propose an experimental method to measure this force and show that its magnitude st…

Depletion-limited Kerr solitons in singly-resonant optical parametric oscillators

Carlos Mas Arabi, Nicolas Englebert, Pedro Parra-Rivas +2

We analyze the impact of pump depletion in the generation of cavity solitons in a singly-resonant parametrical oscillator that includes a $χ^{(3)}$ nonlinear section. We find an an…

Can neutron star mergers alone explain the r-process enrichment of the Milky Way?

Chiaki Kobayashi, Ilya Mandel, Krzysztof Belczynski +9

Comparing Galactic chemical evolution models to the observed elemental abundances in the Milky Way, we show that neutron star mergers can be a leading r-process site only if at low…

Validation and integration tests of the JUNO 20-inch PMTs readout electronics

Vanessa Cerrone, Katharina von Sturm, Marco Bellato +127

The Jiangmen Underground Neutrino Observatory (JUNO) is a large neutrino detector currently under construction in China. JUNO will be able to study the neutrino mass ordering and t…

Telling compositeness at a distance with outer automorphisms and CP

Ingolf Bischer, Christian Döring, Andreas Trautner

We investigate charge-parity (CP) and non-CP outer automorphism of groups and the transformation behavior of group representations under them. We identify situations where composit…

A spectroscopic multiplicity survey of Galactic Wolf-Rayet stars. III. The northern late-type nitrogen-rich sample

K. Dsilva, T. Shenar, H. Sana +1

Massive stars are powerful cosmic engines. In the phases immediately preceding core-collapse, massive stars in the Galaxy with $M_{i} ≳ 20$ $M_{⊙}$ may appear as classical…

X-Shooter Survey of Young Intermediate Mass Stars -- I. Stellar Characterization and Disc Evolution

Daniela P. Iglesias, Olja Panić, Mario van den Ancker +6

Intermediate mass stars (IMSs) represent the link between low-mass and high-mass stars and cover a key mass range for giant planet formation. In this paper, we present a spectrosco…

A Search for Coincident Neutrino Emission from Fast Radio Bursts with Seven Years of IceCube Cascade Events

R. Abbasi, M. Ackermann, J. Adams +382

This paper presents the results of a search for neutrinos that are spatially and temporally coincident with 22 unique, non-repeating Fast Radio Bursts (FRBs) and one repeating FRB…

Caustic-like Structures in UHECR Flux after Propagation in Turbulent Intergalactic Magnetic Fields

K. Dolgikh, A. Korochkin, G. Rubtsov +2

UHECR propagation in a turbulent intergalactic magnetic field in the small-angle scattering regime is well understood for propagation distances much larger than the field coherence…

Quantized valley Hall response from local bulk density variations

Maxime Jamotte, Lucila Peralta Gavensky, Cristiane Morais Smith +2

The application of a mechanical strain to a 2D material can create pseudo-magnetic fields and lead to a quantized valley Hall effect. However, measuring valley-resolved effects rem…

Measurement of the electroweak production of W $γ$ in association with two jets in proton-proton collisions at $s$ = 13 TeV

CMS Collaboration

A measurement is presented for the electroweak production of a W boson, a photon ( $γ$ ), and two jets (j) in proton-proton collisions. The leptonic decay of the W boson is selected…
