1.
The energy spectrum of magnetohydrodynamic turbulence attracts interest due to its fundamental importance and its relevance for interpreting astrophysical data. Here we p [...]
25 October 2012 | Astronomy and Astrophysics | Article |
2.
Non-baryonic dark matter is understood to constitute approximately 27% of the universe's total energy density. Despite its substantial contribution to the cosmic energy b [...]

4.
We present a 3D general-relativistic magnetohydrodynamic simulation of a short-lived neutron star remnant formed in the aftermath of a binary neutron star merger. The sim [...]

5.
The most widely accepted scenario for the formation of the Earth–Moon system involves a dramatic impact between the proto-Earth and some other cosmic body. Many feature [...]
24 October 2022 | Astronomy and Astrophysics | Article |
6.
We study effective field theories (EFTs) enjoying (maximal) biform symmetries. These are defined by the presence of a conserved (electric) current that has the symmetries [...]
15 February 2023 | Astronomy and Astrophysics | Article |
7.
Planetary-scale magnetic fields provide a unique window into a planet's deep interior. From the magnetic field of Earth to that of Jupiter, the existence of such fields i [...]

9.
A retarder is presented for application in systems that transmit radiation through waveguides, such as microwave or millimeter-wave systems. The retarder is a compound de [...]
08 November 2005 | Astronomy and Astrophysics | Patent |
10.
We study the N-point function of the density contrast to quadratic order in the squeezed limit during the matter-dominated (MD) and radiation-dominated (RD) eras in synch [...]
11 August 2023 | Astronomy and Astrophysics; Enrico Fermi Institute | Article |
11.
We develop a model for correlations of cosmic microwave background (CMB) anisotropy on the largest angular scales, based on standard causal geometrical relationships in s [...]
24 July 2023 | Astronomy and Astrophysics | Article |
12.
TOF-PET detector systems, and methods for imaging photon-emitting samples using the detector systems, are provided. The TOF-PET detector systems use large-area photodetec [...]
08 February 2018 | Physics; Astronomy and Astrophysics; Radiology; Enrico Fermi Institute | Patent |
13.
Bayesian Estimation Applied to Multiple Species (BEAMS) is implemented in the BEAMS with Bias Corrections (BBC) framework to produce a redshift-binned Hubble diagram (HD) [...]
18 July 2023 | Astronomy and Astrophysics | Article |
14.
Our concordance cosmological model, known as Lambda-CDM, is remarkably successful in explaining a wide range of observations. Using data to fit that model to we are able [...]
2023-08 | Astronomy and Astrophysics | Dissertation |
15.
We introduce a model for the explicit evolution of interstellar dust in a cosmological galaxy formation simulation. We post-process a simulation from the Cosmic Reionizat [...]

18.
The structure and evolution of wind-blown bubbles (WBBs) around massive stars has primarily been investigated using an energy-conserving model of wind-blown bubbles. Whil [...]
19 June 2023 | Astronomy and Astrophysics | Article |
19.
We present a comprehensive analysis of the mass and light distributions in cluster-scale strong gravitational lens systems. Strong gravitational lensing is a rare phenome [...]
2023-06 | Astronomy and Astrophysics | Thesis |
20.
Intense, high energy stellar irradiation is believed to control the atmospheric mass loss of short-period planets. These effects are most dramatic in the early stages of [...]
2023-06 | Astronomy and Astrophysics | Dissertation |
21.
Black holes that were formed in the early universe, known as primordial black holes, are promising candidates for dark matter. They evaporate in a process known as Hawkin [...]
2023-06 | Astronomy and Astrophysics | Dissertation |
22.
Diagnostic testing may represent a key component in response to an ongoing epidemic, especially if coupled with containment measures, such as mandatory self-isolation, ai [...]

23.
24.
We study the structure of the flat space wavefunctional in scalar field theories with nonlinearly realized symmetries. These symmetries imply soft theorems that are satis [...]
14 March 2023 | Astronomy and Astrophysics | Article |
25.
Presented at the 2022 History of Science Society conference, the poster features the labor being done at Yerkes Observatory in the early 20th century. It features the spe [...]
