Overview

Top Research Topics at Journal of Cosmology and Astroparticle Physics?

Astrophysics, Dark matter, Inflation (cosmology), Theoretical physics and Particle physics are among the topics commonly tackled in the journal. The research on Astrophysics discussed in it draws on the closely related field of Cosmic microwave background. The study of Spectral density and how it intertwines with concepts under Statistical physics were explored in the presented Cosmic microwave background research.

While Dark matter is the key highlight in Journal of Cosmology and Astroparticle Physics, it also covered some subjects on Scalar field dark matter and Dark fluid and Hot dark matter. Journal of Cosmology and Astroparticle Physics addresses concerns in Inflation (cosmology) which are intertwined with other disciplines, such as Field (physics), Non-Gaussianity and Scalar (mathematics). The featured Scalar (mathematics) studies mainly concentrate on Mathematical physics but also cover areas of interest in De Sitter universe.

The presented Theoretical physics research focuses mostly on Gravitation and, on occasion, topics in General relativity. Many of the studies tackled connect Cosmology with a similar field of study like Universe. The study on Cosmological perturbation theory presented in Journal of Cosmology and Astroparticle Physics intersects with subjects under the field of Classical mechanics.

  • Astrophysics (27.48%)
  • Dark matter (24.46%)
  • Inflation (cosmology) (19.27%)

What are the most cited papers published in the journal?

  • The Cosmic Linear Anisotropy Solving System (CLASS). Part II: Approximation schemes (1243 citations)
  • Towards inflation in string theory (1188 citations)
  • Observational signatures and non-Gaussianities of general single-field inflation (941 citations)

Research areas of the most cited articles at Journal of Cosmology and Astroparticle Physics:

The published papers explore disciplines such as Dark matter, Astrophysics, Inflation (cosmology), Particle physics and Cosmology. While the journal publications focused on Astrophysics, they were also able to explore topics like Astronomy and Cosmic microwave background. Non-Gaussianity and Scalar (mathematics) are some topics wherein Inflation (cosmology) research discussed in the journal papers has an impact.

What topics the last edition of the journal is best known for?

  • Quantum mechanics
  • Electron
  • General relativity

The previous edition focused in particular on these issues:

The aim of the journal is to expand the discussion of research in Astrophysics, Dark matter, Particle physics, Inflation (cosmology) and Cosmic microwave background. The close relationship between Spectral density and Statistical physics is one of the points of interest dissected in Astrophysics research. Some problems in Dark matter that were presented in the journal overlapped with concepts under Cosmology, Halo and Annihilation.

The concepts on Particle physics presented in Journal of Cosmology and Astroparticle Physics can also apply to other research fields, including Parameter space and Universe. While work presented in the journal provided substantial information on Inflation (cosmology), it also covered topics in Gravitational wave, Scalar (mathematics) and Mathematical physics. It facilitates discussions on Theoretical physics that incorporate concepts from other fields like Field (physics), Dark energy, Scalar field and Gravity (chemistry).

The most cited articles from the last journal are:

  • Phase Transitions in an Expanding Universe: Stochastic Gravitational Waves in Standard and Non-Standard Histories (56 citations)
  • Probing Primordial Features with the Stochastic Gravitational Wave Background (34 citations)
  • Towards an all-orders calculation of the electroweak bubble wall velocity (30 citations)

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 63.96% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 31.49% were posted by at least one author from the top 10 institutions publishing in the journal. Another 12.34% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 15.32% of all publications and 40.85% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

  • Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
  • Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
  • Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
  • Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
  • Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.
