| Abstract: |
For obtaining a complete picture of galaxies, multi-wavelength observations are crucial to observe their stars, gas, dust, and chemical composition. With Hubble, JWST, and ALMA operating at the same time, we find ourselves in an era where we can jointly observe the UV, optical and infrared light. I present an overview of results obtained by the synergy of these observatories focusing on three new programs with JWST (ALPINE NIRSpec/IFU program and MIRI/MRS PAH survey) and ALMA (CHAMPS 1.2mm survey). These study the chemical compositions of z=4-6 galaxies, search for the most dust-obscured sources during the Epoch of Reionization, and measure for the first time spatially resolved PAH dust emission in z=1 galaxies. Finally, I will also showcase the first spectra from SPHEREx to reveal the PAH emission of low-redshift Euclid-selected galaxies. SPHEREx is a brand-new Caltech-led space telescope providing an all-sky spectroscopic survey from 0.7-5 micro-meters. |
