SNO and Supernovae [PDF]

, 2001
The Sudbury Neutrino Observatory (SNO) has unique capabilities as a supernova detector. In the event of a galactic supernova there are opportunities, with the data that SNO would collect, to constrain certain intrinsic neutrino properties significantly ...

iPTF16geu: A multiply imaged, gravitationally lensed type Ia supernova [PDF]

Science, 2016
Multiple images of a type Ia supernova General relativity indicates that any sufficiently massive object bends the path of light passing by it. This effect is known as gravitational lensing. Goobar et al.

On the occurrence of fast neutrino flavor conversions in multidimensional supernova models [PDF]

Physical Review D, 2018
The dense neutrino medium in a core-collapse supernova or a neutron-star merger event can experience fast flavor conversions on time/distance scales that are much smaller than those of vacuum oscillations.

Magnetic Globe Lithograph [PDF]

, 2004
This activity demonstrates what a dipole magnetic field looks like in 3D. It was developed because the commonly used classroom demo (iron filings on a sheet of paper on top of a bar magnet) leads to student misconception that magnetic fields are two ...

Determining the Supernova Direction by its Neutrinos

, 2002
Supernova neutrinos, which arrive at Earth earlier than light, allow for the earliest determination of the direction of the supernova. The topic of this paper is to study how accurately we can determine the supernova direction.

Supernova Neutrinos: Production, Oscillations and Detection [PDF]

, 2015
Neutrinos play a crucial role in the collapse and explosion of massive stars, governing the infall dynamics of the stellar core, triggering and fueling the explosion and driving the cooling and deleptonization of the newly formed neutron star.

Measuring the supernova unknowns at the next-generation neutrino telescopes through the diffuse neutrino background [PDF]

Journal of Cosmology and Astroparticle Physics, 2018
The detection of the diffuse supernova neutrino background (DSNB) will preciously contribute to gauge the properties of the core-collapse supernova population.

Logarithmic and Strong Coupling Models in Weyl‐Type f(Q,T)$f(Q,T)$ Gravity

Annalen der Physik, EarlyView.
This work explores Weyl‐type f(Q,T) gravity using recent observational datasets — CC, Pantheon+, Union 3.0, and DESI DR2. Through MCMC analysis of logarithmic and strong coupling models, the study reveals a transition from deceleration to acceleration, quintessence‐to‐phantom dynamics, and late‐time consistency with LCDM, offering a geometry‐driven ...
