Reverberation mapping black hole accretion flows
Sitting at the heart of nearly all galaxies is a massive black hole, that, while typically 1000 times less massive than the galaxy in which it resides, has the potential to release enough energy via a...

A Song of Ice and Fire: the Fate of Planetary Systems After Stellar Death
In the past 30 years, astronomers have discovered thousands of planets orbiting stars outside the solar system. Most of the exoplanets we know of today orbit stars that will eventually exhaust their n...

High-resolution spectroscopy of ionized plasmas in the Universe
<p>Ionized plasmas are ubiquitous in the Universe: from stellar coronae to cosmic web filaments. Characterizing ionized plasmas is critical to address many astrophysical questions, for instance, the inte...</p>

The First Census of Metals in Dwarf Galaxies
Metals, conventionally defined as elements heavier than hydrogen and helium, are actively circulated between galaxies and their circumgalactic medium (CGM). Dwarf galaxies are more efficient at propel...

The radio-bright future of studying black holes
<p>In recent years we witnessed tremendous progress in high frequency very long baseline radiointerferometry (VLBI). These developments were most notably marked by the first image of a supermassive black...</p>

Bridging the Gap Between Galaxy and Star Formation with Star Clusters
<p>Over the past decades, the discovery of a large number of young massive clusters (YMCs) in the local Universe and giant clumps in high-z galaxies suggests that clustered star formation is the dominant...</p>

Dynamics and Origins of Planets Around Non-Solar-Type Stars
The search for extrasolar planets initially focused on Sun-like FGK main-sequence stars, but efforts have been made in recent years to search for planets around more massive stars in their giant phase...

Magnetars, a possible engine of FRBs--the first smoking gun from SGR J1935+2154
Fast radio bursts (FRBs) are millisecond radio pulses detected from cosmological distances. A large number of models invoke extragalactic magnetars as the sources of these mysterious events. Magnetars...

Protoplanetary Disk Structure and Young Planet Population
Recent ground based observations at various wavelengths reveal a variety of protoplanetary disk structures. These disk structures may help us to constrain the planet formation process. We apply the pl...
