The cosmic microwave background (CMB), a remnant of the Big Bang, provides unparalleled insights into the primordial universe, its energy content, and the origin of cosmic structures. The success of forthcoming terrestrial and space experiments hinge

All We Are Is Dust In The WIM: Constraints on Dust Properties in the Milky Way's Warm Ionized Medium

Autor: West, J. L., Gaensler, B. M., Miville-Deschênes, M. -A., Mahajan, N., Dechant, J., Boulanger, F., Martin, P. G., Zelko, I. A.

We present a comparison of the presence and properties of dust in two distinct phases of the Milky Way's interstellar medium: the warm neutral medium (WNM) and the warm ionized medium (WIM). Using distant pulsars at high Galactic latitudes and vertic

Multi-phase gas interactions on subarcsec scales in the shocked IGM of Stephan's Quintet with JWST and ALMA

Autor: Appleton, P. N., Guillard, P., Emonts, B., Boulanger, F., Togi, A., Reach, W. T., Alatalo, K., Cluver, M., Santos, T. Diaz, Duc, P-A., Gallagher, S., Ogle, P., O'Sullivan, E., Voggel, K., Xu, C. K.

We combine JWST and HST imaging with ALMA~CO(2-1) spectroscopy to study the highly turbulent multi-phase intergalactic medium (IGM) in Stephan's Quintet on 25-150 pc scales. Previous Spitzer observations revealed luminous H$_2$ line cooling across a

The CO emission in the Taffy Galaxies (UGC 12914/5) at 60pc resolution-I: The battle for star formation in the turbulent Taffy Bridge

Autor: Appleton, P. N., Emonts, B., Lisenfeld, U., Falgarone, E., Guillard, P., Boulanger, F., Braine, J., Ogle, P., Struck, C., Vollmer, B., Yeager, T.

We present ALMA observations at a spatial resolution of 0.2 arcsec (60 pc) of CO emission from the Taffy galaxies (UGC 12914/5). The observations are compared with narrow-band Pa$\alpha$, mid-IR, radio continuum and X-ray imaging, plus optical spectr
