A graph-based spectral classification of Type II supernovae
(2023-06-06)
Given the ever-increasing number of time-domain astronomical surveys, employing robust, interpretative, and automated data-driven classification schemes is pivotal. Based on graph theory, we present new data-driven ...
Translators of Galaxy Morphology Indicators between Observation and Simulation
(2023-06-06)
Based on the recent advancements in numerical simulations of galaxy formation, we anticipate the achievement of realistic models of galaxies in the near future. Morphology is the most basic and fundamental property of ...
VICTORIA project: The LOFAR HBA Virgo Cluster Survey
(2023-06-02)
Context. The Virgo cluster is the nearest (d = 16.5 Mpc) massive (M ≥ 1014 M) galaxy cluster and is therefore a prime target for studying astrophysical processes in dense large-scale environments. In the radio band, we can ...
The puzzle of the formation of T8 dwarf Ross 458c
(2023-06-01)
At the lowest masses, the distinction between brown dwarfs and giant exoplanets is often blurred and literature classifications rarely reflect the deuterium burning boundary. Atmospheric characterization may reveal the ...
Radio galaxy zoo EMU: towards a semantic radio galaxy morphology taxonomy
(2023-06-01)
We present a novel natural language processing (NLP) approach to deriving plain English descriptors for science cases otherwise restricted by obfuscating technical terminology. We address the limitations of common radio ...
VISIONS: The VISTA Star Formation Atlas
(2023-05-31)
VISIONS is an ESO public survey of five nearby (d < 500 pc) star-forming molecular cloud complexes that are canonically associated with the constellations of Chamaeleon, Corona Australis, Lupus, Ophiuchus, and Orion. The ...
Kinematics, Structure, and Mass Outflow Rates of Extreme Starburst Galactic Outflows
(2023-05-19)
We present results on the properties of extreme gas outflows in massive (M * ∼ 1011 M ⊙), compact, starburst (star formation rate, SFR∼ 200 M ⊙ yr−1) galaxies at z = 0.4–0.7 with very high star formation surface densities ...
The hyperluminous X‐ray source population
(2023-05-16)
We have recently published a catalog of 1843 candidate ultraluminous X‐ray sources (ULXs). This is the largest catalog of ULXs to date and was built by cross‐correlating recent serendipitous source catalogs from the ...
The Diffuse Ionized Gas Halo of the Large Magellanic Cloud
(2023-05-15)
The Large Magellanic Cloud (LMC) has an extensive Hα emission halo that traces an extended, warm ionized component of its interstellar medium. Using the Wisconsin Hα Mapper telescope, we present the first kinematic Hα ...
New mechanisms for forming multiple hotspots in radio jets
(2023-05-01)
Hotspots of radio galaxies are regions of shock-driven particle acceleration. Multiple hotspots have long been identified as potential indicators of jet movement or precession. Two frequent explanations describe a secondary ...
