[2022 Spring Semester] Astronomy Instrumentation at the AAO

The AAO has long and successful history in developing astronomical instruments for many of world's premier telescopes. The AAO now sits as a department of Macquarie University and is a key node of the Astralis Instrumentation Consortium. This talk will present an overview of our current programme including a description of our flagship hardware projects (such as 4MOST, MANIFEST, GHOST, […]

[2022 Spring Semester] Multi-wavelength view of dust-obscured AGN

I will review the physical and statistical properties of dust-obscured AGN viewed with multi-wavelength data. In particular, I mainly focus on infrared (IR)-bright dust-obscured galaxies (DOGs) with i – [22] > 7.0 in AB magnitude and with flux density at 22 ｵ m > 1.0 mJy. IR-bright DOGs are a subset of high-redshift (z~1-3) optically-faint luminous IR galaxies (such as […]

[2022 Spring Semester] Evolution of Galaxy Pairs Induced by Both Gravitational and Hydrodynamic Interactions

Galaxy interactions play an important role in galaxy evolution. Numerous studies have pointed out that interacting galaxies have unique characteristics in many aspects such as morphology, star formation, metallicity, AGN activity, and spin angular momentum. While the interaction-induced evolution is usually ascribed to the gravitational tidal effect of neighboring galaxies, recent studies have identified the […]

[2022 Spring Semester] Variability in Young Stellar Objects

One of the main properties of young stellar objects (YSOs) is that they typically display brightness variability. This is true across all stages of young stellar evolution, and is observed over a wide range in wavelength (optical to sub-mm) and timescales (from a few hours to 100 yrs). This variability can be caused by various […]
