We have explored the properties of a peculiar object detected in deep optical imaging and located at the tip of an H I tail emerging from Hickson Compact Group...

PublicationA fast bar in the post-interaction galaxy NGC 1023
We measured the bar pattern speed, Ωp , of the SB0 galaxy NGC 1023 using the Tremaine-Weinberg method with stellar-absorption slit spectroscopy. The morphology...

PublicationA giant thin stellar stream in the Coma Galaxy Cluster
The study of dynamically cold stellar streams reveals information about the gravitational potential where they reside and provides important constraints on the...

PublicationA K band survey in the Groth Strip Flanking Fields
As a part of our collaboration in the COSMOS Project, devoted to the characterization of galaxies during the epoch of maximum star formation in the history of...

PublicationA K-band central disc surface brightness correlation with scalelength for early-type disc galaxies, and the inclination correction
The K-band light profiles from two statistically complete, diameter-limited samples of disc galaxies have been simultaneously modelled with a seeing-convolved...

PublicationA Massive Hot Jupiter Orbiting a Metal-rich Early M Star Discovered in the TESS Full-frame Images
Observations and statistical studies have shown that giant planets are rare around M dwarfs compared with Sun-like stars. The formation mechanism of these...

PublicationA Morphological Type Dependence in the μ0-log h Plane of Spiral Galaxy Disks
We present observational evidence for a galaxy ``type'' dependence to the location of a spiral galaxy's disk parameters in the μ0-logh plane. With a sample of...

PublicationA Multi-epoch, Multiwavelength Study of the Classical FUor V1515 Cyg Approaching Quiescence
Historically, FU Orionis-type stars are low-mass, pre-main-sequence stars. The members of this class experience powerful accretion outbursts and remain in an...

PublicationA Near-infrared Census of the Multicomponent Stellar Structure of Early-type Dwarf Galaxies in the Virgo Cluster
The fraction of star-forming to quiescent dwarf galaxies varies from almost infinity in the field to zero in the centers of rich galaxy clusters. What is...
