Deep Transfer Learning for Classification of Variable Sources
Dae-Won Kim, Doyeob Yeo, Coryn A. L. Bailer-Jones +1
Ongoing or upcoming surveys such as Gaia, ZTF, or LSST will observe light-curves of billons or more astronomical sources. This presents new challenges for identifying interesting a…
Core-Jet Blending Effects in Active Galactic Nuclei under the Korean VLBI Network View at 43 GHz
Juan-Carlos Algaba, Jeffrey Hodgson, Sin-Cheol Kang +5
A long standing problem in the study of Active Galactic Nuclei (AGNs) is that the observed VLBI core is in fact a blending of the actual AGN core (classically defined by the …
The Power of Simultaneous Multi-frequency Observations for mm-VLBI: Beyond Frequency Phase Transfer
Guang-Yao Zhao, Juan Carlos Algaba, Sang-Sung Lee +15
Atmospheric propagation effects at millimeter wavelengths can significantly alter the phases of radio signals and reduce the coherence time, putting tight constraints on high frequ…
An improved quasar detection method in EROS-2 and MACHO LMC datasets
Karim Pichara, Pavlos Protopapas, Dae-Won Kim +2
We present a new classification method for quasar identification in the EROS-2 and MACHO datasets based on a boosted version of Random Forest classifier. We use a set of variabilit…
