Galaxy Phase-Space Density Data Preclude That Bose–Einstein Condensate Be the Total Dark Matter

Universe, 2022
Ultralight scalars with a typical mass of the order m∼10−22 eV and light scalars forming a Bose–Einstein condensate (BEC) exhibit a Jeans length in the kpc scale and were therefore proposed as dark matter (DM) candidates.

Targeted decrease of portal hepatic pressure gradient improves ascites control after TIPS

Hepatology, EarlyView., 2022
The river diagram demonstrates that after transjugular intrahepatic portosystemic shunt insertion (TIPS) the majority of patients without ascites and 50% of the patients with ascites detectable at ultrasound, show the best response in the long term follow‐up.

Janus kinase 2 inhibition by pacritinib as potential therapeutic target for liver fibrosis

Hepatology, EarlyView., 2022
Diagram of the activation of the profibrotic and procontractile Janus kinase 2 (JAK2)/Ras homolog family member A/Rho‐kinase pathway and the inhibition of phosphorylated JAK2 by pacritinib to inhibit hepatic stellate cell activity. Abstract Background and Aims Janus kinase 2 (JAK2) signaling is increased in human and experimental liver fibrosis with ...

A new (2+1)D cluster finding algorithm based on photometric redshifts: large scale structure in the Chandra Deep Field South [PDF]

, 2006
Aims: We study galaxy clustering and explore the dependence of galaxy properties on the the environment up to a redshift z~1, on the basis of a deep multi-band survey in the Chandra Deep Field South.

Spiral structure in external galaxies [PDF]

Symposium - International Astronomical Union, 1970
The need for observing at least four different categories of optical objects for a satisfactory definition of optical spiral structure is emphasized. A sequence of optical form-types for the description of spiral structure is outlined. A pronounced difference in the nature of the spiral structure of the outer and inner parts of Messier 33 is ...

Translators of Galaxy Morphology Indicators between Observation and Simulation

The Astrophysical Journal, 2023
Based on the recent advancements in numerical simulations of galaxy formation, we anticipate the achievement of realistic models of galaxies in the near future.

Dynamics of the Spiral-Arm Corotation and Its Observable Footprints in the Solar Neighborhood

Frontiers in Astronomy and Space Sciences, 2021
This article discusses the effects of the spiral-arm corotation on the stellar dynamics in the Solar Neighborhood (SN). All our results presented here rely on: (1) observational evidence that the Sun lies near the corotation circle, where stars rotate ...

Two-point Correlation Function Studies for the Milky Way: Discovery of Spatial Clustering from Disk Excitations and Substructure

The Astrophysical Journal, 2023
We introduce a two-particle correlation function (2PCF) for the Milky Way, constructed to probe spatial correlations in the orthogonal directions of the stellar disk in the Galactic cylindrical coordinates of R , ϕ , and z . We use this new tool to probe

THE ALIGNMENT OF GALAXY STRUCTURES

The Astrophysical Journal, 2015
We analyzed the orientation of the sample of ACO galaxy clusters. We examined the alignment in a subsample of 1056 galaxy structures taken from the Panko–Flin (2006) Catalog with known BM morphological types. We were looking for a correlation between the orientation of the cluster and the positions of neighboring clusters.

A galaxy-halo model of large-scale structure [PDF]

, 2005
We present a new, galaxy-halo model of large-scale structure, in which the galaxies entering a given sample are the fundamental objects. Haloes attach to galaxies, in contrast to the standard halo model, in which galaxies attach to haloes.
