Global well-posedness of the two-dimensional stochastic nonlinear wave equation on an unbounded domain

Leonardo Tolomeo

We study the two-dimensional wave equation with cubic nonlinearity posed on , with space-time white noise forcing. After a suitable renormalisation of the nonlinearity…

The Tarantula Massive Binary Monitoring: III. Atmosphere analysis of double-lined spectroscopic systems

L. Mahy, H. Sana, M. Abdul-Masih +17

Accurate stellar parameters of individual objects in binary systems are essential to constrain the effects of binarity on stellar evolution. These parameters serve as a prerequisit…

The Tarantula Massive Binary Monitoring. IV. Double-lined photometric binaries

L. Mahy, L. A. Almeida, H. Sana +10

A high fraction of massive stars are found to be binaries but only a few of them are reported as photometrically variable. By studying the populations of SB2 in the 30 Doradus regi…

Human Motion Anticipation with Symbolic Label

Julian Tanke, Andreas Weber, Juergen Gall

Anticipating human motion depends on two factors: the past motion and the person's intention. While the first factor has been extensively utilized to forecast short sequences of hu…

On the formation of exotic, massive, stellar-remnant black holes at solar and sub-solar metallicities through evolution of massive binaries

Sambaran Banerjee

The recent inference of a 70M_sun black hole (BH) in the Galactic, detached binary LB-1 has sparked cross-disciplinary debate since a stellar remnant of such large mass is well abo…

Circalunar variations of the night sky brightness -- an FFT perspective on the impact of light pollution

Johannes Puschnig, Stefan Wallner, Thomas Posch

Circa-monthly activity conducted by moonlight is observed in many species on Earth. Given the vast amount of artificial light at night (ALAN) that pollutes large areas around the g…
