Astronomy with energy dependent flavour ratios of extragalactic neutrinos
Journal of High Energy Physics, 2021 High energy astrophysical neutrinos interacting with ultralight dark matter (DM) can undergo flavour oscillations that induce an energy dependence in the flavour ratios.

Extragalactic Astronomy with the VLTI: a new window on the Universe [PDF]
Astrophysics and Space Science, 2003 Interferometry in the optical and near infrared has so far played a marginal role in Extragalactic Astronomy. Active Galactic Nuclei are the brightest and most compact extragalactic sources, nonetheless only a very limited number could be studied with speckle interferometry and none with long baseline interferometry.

The Supersonic Project: Star Formation in Early Star Clusters without Dark Matter
The Astrophysical Journal Letters, 2023 The formation mechanism of globular clusters (GCs) has long been debated by astronomers. It was recently proposed that supersonically induced gas objects (SIGOs)–which formed in the early Universe due to the supersonic relative motion of baryons and dark

Symmetries in Stellar, Galactic, and Extragalactic Astronomy [PDF]
, 2021 Examples are presented for appearance of geometric symmetry in the shape of various astronomical objects and phenomena. Usage of these symmetries in astrophysical and extragalactic research is also discussed.

Proton and neutrino extragalactic astronomy [PDF]
Physical Review D, 2008 The study of extragalactic sources of high energy radiation via the direct measurement of the proton and neutrino fluxes that they are likely to emit is one of the main goals for the future observations of the recently developed air showers detectors and neutrino telescopes. In this work we discuss the relation between the inclusive proton and neutrino

Extragalactic Astronomy and IUE [PDF]
Highlights of Astronomy, 1980 The first thing to say is that IUE has been a great success and we should all congratulate the agencies in the U.S.A., Europe and the U.K. and the many scientists and engineers involved in the project on making it possible. In surveying what has been achieved so far, it is important to remember that we may well have IUE with us for a further 3 or even ...

TeV GAMMA RAYS: OBSERVATIONS VERSUS EXPECTATIONS & THEORY
Acta Polytechnica, 2013 The scope of this paper is to discuss two important questions relevant for TeV γ-ray astronomy; the pursuit to reveal the origin of cosmic rays in our galaxy, and the opacity of the universe in γ-rays.

The Astrophysical Journal Supplement Series, 2023 JWST has revolutionized the field of extragalactic astronomy with its sensitive and high-resolution infrared view of the distant Universe. Adding to the new legacy of JWST observations, we present the first NIRCam imaging data release from the JWST ...
