Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Merger-induced star formation in low-metallicity dwarf galaxy NGC 4809/4810
Get PDFThe physical mechanisms driving starbursts in dwarf galaxies are unclear, and
the effects of mergers on star formation in these galaxies are still uncertain.
We explore how the merger process affects star formation in metal-poor dwarf
galaxies by analyzing high-spatial-resolution ( 70 pc) integral field
spectrograph observations of ionized gas. We use archival data from the Very
Large Telescope/Multi Unit Spectroscopic Explorer to map the spatial
distribution of strong emission lines (e.g., , , , , etc) in the nearby merging
star-forming dwarf galaxy system NGC 4809/4810. We identify approximately 112
star-forming knots scattered among the two galaxies, where the gas-phase
metallicity distribution is inhomogeneous and mixing with metal-poor and
metal-rich ionized gas. Star-forming knots at the interacting region show lower
metallicity, the highest star formation rates (SFRs) and SFR to resolved
main-sequence-relation (rMSR) ratios. Ionized gas exhibits an obvious
northeast-southwest velocity gradient in NGC 4809, while seemingly mixed in NGC
4810. High virial parameters and the stellar mass-size relation of HII regions
indicate that these regions are dominated by direct radiation pressure from
massive stars/clusters and persistently expanding. We find two different
stellar mass surface density-stellar age relations in NGC 4809 and NGC 4810,
and the stellar ages of NGC 4810 are systematically younger than in NGC 4809.
Our study suggests that the merging stage of two dwarf galaxies can induce
starburst activities at the interaction areas, despite the metal-deficient
environment. Considering the high specific SFRs and different stellar ages, we
propose that the interaction initially triggered star formation in NGC 4809 and
then drove star formation in NGC 4810.Comment: 13 pages, 12 figures; accepted for publication in A&
