The Intrinsic Flattening of Galaxy Disks
The Astrophysical JournalHighly inclined (edge-on) disk galaxies offer the unique perspective to constrain their intrinsic flattening, c / a , where c and a are, respectively, the vertical and long radial axes of the disk measured at suitable stellar densities.

Exploration of Halo Substructures in Integrals-of-motion Space with Gaia Data Release 3
The Astrophysical JournalUsing kinematic data from the Gaia Data Release 3 catalog, along with metallicity estimates robustly derived from Gaia BP/RP spectra, we have explored the Galactic stellar halo in search of both known and potentially new substructures.

Distribution and Kinematics of Classical Cepheids in the Galactic Outer Ring
Open Astronomy, 2015 The existence of an outer ring in the Galaxy can explain the kinematics of OB associations in the Perseus and Sagittarius stellar-gas complexes. Moreover, it can also explain the orientation of the Carina arm with respect to the major axis of the bar. We

The Neutral Hydrogen Kinematics of the Dwarf Galaxy Merger NGC 3239 [PDF]
, 2019 We present H I spectral line images of the nearby dwarf galaxy NGC 3239. The galaxy’s curious morphology suggests that it is a post-merger system. We propose that NGC 3239 is a merger because it has multiple tidal tails, an enhanced velocity dispersion ...

Dynamics of the Boxy Elliptical Galaxy NGC 1600
, 1998 We use three--integral models to infer the distribution function (DF) of the boxy E3-E4 galaxy NGC 1600 from surface brightness and line profile data on the minor and major axes.

Ecography, EarlyView.Developing species distribution models (SDMs) requires high‐quality species occurrence records. These records, stemming from various sources with different sampling procedures, are often archived in open‐access databases, making automated data quality checks inevitable.

Quaternary Habitat Fluctuations and Demographic Dynamics in Turtles Inferred From Environmental Niche Modelling and Whole Genome Data. [PDF]
Mol Ecol ResourABSTRACT Quaternary climatic fluctuations had a substantial influence on ecosystems, species distribution, phenology and genetic diversity, driving extinction, adaptation and demographic shifts during glacial periods and postglacial expansions. Integration of genomic data and environmental niche modelling can provide valuable insights on how organisms ...

ESC Heart Failure, EarlyView.This state‐of‐the‐art review outlines a practical, evidence‐based framework for early acute heart failure management to address critical gaps in current guidance and improve early treatment outcomes. Key components include early identification of co‐existing conditions, bedside haemodynamic profiling, a structured diagnostic approach incorporating both
