Bose-Einstein and Other Correlations in Hadronic Z Decay

, 2003
In hadronic Z decays, Bose-Einstein correlations in neutral pion pairs are compared to those in identical charged pion pairs. Bose-Einstein correlations are also measured in triplets of identical charged pions, and comparison with those in pairs of pions

Discovery of an Apparent Red, High-velocity Type Ia Supernova at z = 2.9 with JWST

The Astrophysical Journal Letters
We present the James Webb Space Telescope (JWST) discovery of SN 2023adsy, a transient object located in a host galaxy JADES-GS+53.13485−27.82088 with a host spectroscopic redshift of 2.903 ± 0.007.

The Polar Vortex Hypothesis: Evolving, Spectrally Distinct Polar Regions Explain Short- and Long-term Light-curve Evolution and Color–Inclination Trends in Brown Dwarfs and Giant Exoplanets

The Astrophysical Journal Letters
Recent studies revealed viewing-angle-dependent color and spectral trends in brown dwarfs, as well as long-term photometric variability (∼100 hr). The origins of these trends are yet unexplained.

Stellar contributions to the hard X-ray galactic ridge [PDF]

The number density of serendipitous sources in galactic plane Einstein Observatory IPC fields are compared with predictions based on the intensity of the HEAO-1 A2 unresolved hrd X-ray galactic ridge emission. It is concluded that theoretically predicted

First Mapping of Prebiotic Molecule CH2NH in a Prestellar Core

The Astrophysical Journal Letters
We present the first spatially resolved map of methanimine (CH _2 NH) in the prestellar core L1544 using the IRAM 30 m telescope. The 2 _0,2 –1 _0,1 line at 127 GHz was mapped with 20″ resolution (∼2800 au), revealing extended CH _2 NH emission across ...

MUSEQuBES: Unveiling Cosmic Web Filaments at z ≈ 3.6 through Dual Absorption and Emission Line Analysis

The Astrophysical Journal Letters
According to modern cosmological models, galaxies are embedded within cosmic filaments, which supply a continuous flow of pristine gas, fueling star formation and driving their evolution. However, due to their low density, the direct detection of diffuse

Measuring Scaling Relations: Fitting Technique Matters

The Astrophysical Journal Letters
Scaling relationships, both integrated and spatially resolved, arise owing to the physical processes that govern galaxy evolution and are frequently measured in both observed and simulated data.
