Nuclear regions of ultraluminous and luminous infrared galaxies (U/LIRGs) are powered by starbursts and/or active galactic nuclei (AGNs). These regions are often obscured by extrem…
The ALCHEMI atlas: principal component analysis reveals starburst evolution in NGC 253
Nanase Harada, David S. Meier, Sergio Martín +24
Molecular lines are powerful diagnostics of the physical and chemical properties of the interstellar medium (ISM). These ISM properties, which affect future star formation, are exp…
Large-Scale Features of the CON Galaxy NGC4418 with MUSE
C. F. Wethers, S. Aalto, G. C. Privon +6

Star cluster formation in the most extreme environments: Insights from the HiPEEC survey
A. Adamo, K. Hollyhead, M. Messa +14
We present the Hubble imaging Probe of Extreme Environments and Clusters (HiPEEC) survey. We fit HST NUV to NIR broadband and H fluxes, to derive star cluster ages, masses, exti…
ALMA resolves the remarkable molecular jet and rotating wind in the extremely radio-quiet galaxy NGC 1377
S. Aalto, N. Falstad, S. Muller +14
Submillimetre and millimetre observations are important in probing the properties of the molecular gas and dust around obscured active galactic nuclei (AGNs) and their feedback. Wi…
A spectral stacking analysis to search for faint outflow signatures in z~6 quasars
F. Stanley, J. B. Jolly, S. König +1
Outflows in quasars during the early epochs of galaxy evolution are an important part of the feedback mechanisms potentially affecting the evolution of the host galaxy. However, sy…
The hidden heart of the luminous infrared galaxy IC 860 I. A molecular inflow feeding opaque, extreme nuclear activity
S. Aalto, S. Muller, S. König +19
High-resolution (0."03 - 0."09) (9 - 26 pc)) ALMA (100 - 350 GHz (3 - 0.8 mm)) and VLA 45 GHz measurements have been used to image continuum and spectral line emission from the inn…
Hidden or missing outflows in highly obscured galaxy nuclei?
N. Falstad, F. Hallqvist, S. Aalto +19
Understanding the nuclear growth and feedback processes in galaxies requires investigating their often obscured central regions. One way to do this is to use (sub)millimeter line e…

N. Nesvadba, R. Canameras, R. Kneissl +5
The bright [CI] 1-0 and [CI] 2-1 lines of atomic carbon are becoming more and more widely employed tracers of the cold neutral gas in high-redshift galaxies. Here we present observ…
