We present the Blue Jay survey, a Cycle-1 JWST program aimed at studying the stellar and gas content of galaxies at Cosmic Noon. The survey consists of deep spectroscopy for 153...

Giant planets are expected to predominantly form beyond the water-ice line and occasionally undergo inward migration. Unlike hot Jupiters, which can result from...

The environment plays a key role in galaxy evolution, yet it remains unclear how detailed molecular gas properties and their connection to star formation and stellar content are...

The evolution of protoplanetary discs is intertwined with the process of planet formation, growth and migration. Studies of nearby star-forming regions of different ages and...

The Transiting Exoplanet Survey Satellite (TESS) has identified several thousand planet candidates orbiting a wide variety of stars, and has provided an exciting opportunity for...

We present a comprehensive analysis of variability in young stellar objects (YSOs) using a decade-long mid-infrared photometric dataset from the unTimely catalog. With its...

We present a homogeneous spectroscopic analysis of confirmed Kepler's extended mission (K2) exoplanet-hosting stars, comprising 301 targets with high-resolution optical spectra...

Brown dwarfs are essential probes of stellar and planetary formation, yet their low luminosities pose challenges for detection at large Galactic distances. The James Webb Space...

Transiting exoplanet atmospheric characterization is currently in a golden age as dozens of exoplanet atmospheres are being studied by NASA's Hubble and James Webb Space...

A key property of massive stars is their high degree of multiplicity, which can impact their evolution and end-of-life products. The Southern Massive Stars at High Angular...

Over the last few years, both Atacama Large Millimeter/submillimeter Array (ALMA) and Spitzer observations have revealed a population of likely massive galaxies at z > 3 that...

How does the host galaxy morphology influence a central quasar or vice versa? We address this question by measuring the asymmetries of 2424 SDSS quasar hosts at 0.2 < z <...

The MgII h&k emission lines (2803, 2796{AA}) are a useful tool for understanding stellar chromospheres and transition regions due to their intrinsic brightness, relatively...

One technique for determining stellar ages is to compare the position of a star in the Hertzsprung-Russell diagram to theoretical stellar evolutionary tracks. The sub-giant...

The 'Triangal' galaxy evolution schema is used to assess whether the Tuning Fork (bar strength) or the van den Bergh Trident and ATLAS Comb (spiral strength) offer greater...

Dwarf galaxies are excellent cosmological probes, because their shallow potential wells make them very sensitive to the key processes that drive galaxy evolution, including...

The Survey for Distant Solar Twins aims to find stars very similar to the Sun at distances of 1-4kpc, several times more distant than any currently known solar twins and...

The observed properties of galaxies are strongly dependent on both their total stellar mass and their morphology. Furthermore, the environment is known to play a strong role in...

We present a homogeneous analysis of all DA stars labelled as magnetic in the Montreal White Dwarf Database. Our sample is restricted to almost all known magnetic white dwarf...

We present the kinematic analysis of 246 stars within 4' from the center of Orion Nebula Cluster (ONC), the closest massive star cluster with active star formation across the...
