Facilitating Reproducibility in Catalysis Research with Managed Workflows and RO‐Crates: A Galaxy Case Study

ChemCatChem, Accepted Article.
Publishing supporting data significantly impacts researchers' productivity, especially in experiments requiring extensive tracking of data, processing steps, parameters, and outputs. A managed workflow environment, combined with RO‐Crates, addresses these data management challenges. Workflows provide an alternative for handling complex data analyses by

The cosmological constant derived via galaxy groups and clusters

European Physical Journal C: Particles and Fields, 2019
The common nature of dark matter and dark energy is argued in Gurzadyan (Eur Phys J Plus 134:14, 2019) based on the approach that the cosmological constant $$\varLambda $$ Λ enters the weak-field General Relativity following from Newton theorem on the ...

Evolution of dwarf galaxies in the Centaurus A group [PDF]

, 2007
We consider star formation properties of dwarf galaxies in Cen A group observed within our HST/ACS projects number 9771 and 10235. We model color-magnitude diagrams of the galaxies under consideration and measure star formation rate and metallicity dependence on time.

Hot Gas in Galaxy Groups: Recent Observations

, 2012
Galaxy groups are the least massive systems where the bulk of baryons begin to be accounted for. Not simply the scaled-down versions of rich clusters following self-similar relations, galaxy groups are ideal systems to study baryon physics, which is ...

Introducing the Condor Array Telescope. VI. Discovery of Extensive Ionized Gaseous Filaments of the Cosmic Web in the Direction of the M81 Group

The Astrophysical Journal
We used the Condor Array Telescope to obtain deep imaging observations through luminance broadband and He ii , [O iii ], He i , H α , [N ii ], and [S ii ] narrowband filters of an extended region of the M81 Group spanning ≈8 × 8 deg ^2 on the sky ...

An Extensive Catalog of Early-type Dwarf Galaxies in the Local Universe: Morphology and Environment

The Astrophysical Journal Supplement Series, 2023
We present an extensive catalog of 5405 early-type dwarf (dE) galaxies located in the various environments, i.e., clusters, groups, and fields, of the local universe ( z < 0.01). The dEs are selected through visual inspection of the Legacy survey’s g – r

Pre-Processing and Post-Processing in Group-Cluster Mergers [PDF]

, 2013
Galaxies in clusters are more likely to be of early type and to have lower star formation rates than galaxies in the field. Recent observations and simulations suggest that cluster galaxies may be `pre-processed' by group or filament environments and that galaxies that fall into a cluster as part of a larger group can stay coherent within the cluster ...

A review of multiscale numerical modeling of rock mechanics and rock engineering

Deep Underground Science and Engineering, EarlyView.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...
