We present cosmological constraints from the analysis of two-point correlation functions between galaxy positions and galaxy lensing measured in Dark Energy Survey (DES) Year 3 data and measurements of cosmic microwave background (CMB) lensing from the South Pole Telescope (SPT) and Planck. When jointly analyzing the DES-only two-point functions

We present JWST/MIRI MRS spectroscopy of three Seyfert AGN in which we compare their nuclear Polycyclic Aromatic Hydrocarbons (PAHs) emission with that of star-forming regions. This study, for the first time, investigates local luminous Seyferts (L bol > 10 44.46 erg/s) over a wide wavelength range (4.9-28.1 μm) using sub-arcsecond angular

The bulk of stellar and black hole mass buildup in galaxies occurs in the high-redshift Universe in short, intense bursts of star formation and black hole accretion. However, the exact role of these two processes in assembling galaxies, as well as how much they affect one another, remains unclear. It is thus important to create case studies of high

Hubble's Wide Field Camera 3 (WFC3) is the workhorse instrument for HST, providing direct (staring) and scanning modes using filters and grisms, covering from the near-IR to near-UV. Installed during the most recent HST servicing mission in 2009, WFC3 has logged almost 300,000 observations resulting in exciting scientific discoveries over the past

Hot Jupiters orbiting extremely close to their host star may experience atmospheric escape due to the large amounts of high-energy radiation they receive. Understanding the conditions under which this occurs is critical, as atmospheric escape is believed to be a driving factor in sculpting planetary populations. In recent years, the near-infrared
