Investigating the role of turbulence in the interstellar medium in dusty star-forming galaxies using kpc-resolution ALMA dust and gas maps
B. A. Westoby, J. A. Hodge, P. Sharda +28
We present ALMA high-resolution (0.25/2 kpc) CO(5-4) and CO(4-3) observations of three submillimetre-selected dusty galaxies from the ALESS survey.…
JWST MIRI/MRS observations of hot molecular gas in an AGN host galaxy at Cosmic Noon
D. Kakkad, V. Mainieri, Takumi S. Tanaka +27
Active Galactic Nuclei (AGN) are believed to play a central role in quenching star formation by removing or destroying molecular gas from host galaxies via radiation-pressure drive…
Connection between steep radio spectral slopes and dust extinction in QSOs: evidence for outflow-driven shocks in dusty QSO
V. A. Fawcett, C. M. Harrison, D. M. Alexander +9
Recent studies have found a striking positive correlation between the amount of dust obscuration and enhanced radio emission in quasi-stellar objects (QSOs). However, what causes t…
Unveiling AGN Outflows: [O iii] Outflow Detection Rates and Correlation with Low-Frequency Radio Emission
Emmy L. Escott, Leah K. Morabito, Jan Scholtz +10
Some Active Galactic Nuclei (AGN) host outflows which have the potential to alter the host galaxy's evolution (AGN feedback). These outflows have been linked to enhanced radio emis…
KASHz+SUPER: Evidence of cold molecular gas depletion in AGN hosts at cosmic noon
E. Bertola, C. Circosta, M. Ginolfi +32
The energy released by AGN has the potential to heat or remove the gas of the ISM, thus likely impacting the cold molecular gas reservoir of host galaxies at first, with star forma…
The ALMA-CRISTAL Survey: Spatial extent of [CII] line emission in star-forming galaxies at
Ryota Ikeda, Ken-ichi Tadaki, Ikki Mitsuhashi +24
We investigate the spatial extent and structure of the [CII] line emission in a sample of 34 galaxies at from the ALMA-CRISTAL Survey. By modeling the [CII] line emission i…
The cold molecular gas in z6 quasar host galaxies
Melanie Kaasinen, Bram Venemans, Kevin C. Harrington +8
Probing the molecular gas reservoirs of z>~6 quasar (QSO) host galaxies is fundamental to understanding the coevolution of star formation and black hole growth in these extreme sys…
How does the radio enhancement of broad absorption line quasars relate to colour and accretion rate?
J. W. Petley, L. K. Morabito, A. L. Rankine +8
The origin of radio emission in different populations of radio-quiet quasars is relatively unknown, but recent work has uncovered various drivers of increased radio-detection fract…
At the end of cosmic noon: Short gas depletion times in unobscured quasars at 1
M. Frias Castillo, M. Rybak, J. Hodge +8
Unobscured quasars (QSOs) are predicted to be the final stage in the evolutionary sequence from gas-rich mergers to gas-depleted, quenched galaxies. Studies of this population, how…
Ubiquitous radio emission in quasars: predominant AGN origin and a connection to jets, dust and winds
G. Calistro-Rivera, D. M. Alexander, C. M. Harrison +16
We present a comprehensive study of the physical origin of radio emission in optical quasars at redshifts z < 2.5. We focus particularly on the associations between compact radio e…
Quasar Feedback Survey: molecular gas affected by central outflows and by ~10 kpc radio lobes reveal dual feedback effects in `radio quiet' quasars
A. Girdhar, C. M. Harrison, V. Mainieri +17
We present a study of molecular gas, traced via CO (3-2) from ALMA data, of four z< 0.2, `radio quiet', type 2 quasars (log [L(bol)/(erg/s)] = 45.3 - 46.2; log [L(1.4 GHz)/(W/Hz)]…
The ALMA-CRISTAL survey: Widespread dust-obscured star formation in typical star-forming galaxies at z=4-6
Ikki Mitsuhashi, Ken-ichi Tadaki, Ryota Ikeda +29
We present the morphological parameters and global properties of dust-obscured star formation in typical star-forming galaxies at z=4-6. Among 26 galaxies composed of 20 galaxies o…
The Quasar Feedback Survey: characterising CO excitation in quasar host galaxies
S. J. Molyneux, G. Calistro Rivera, C. De Breuck +15
We present a comprehensive study of the molecular gas properties of 17 Type 2 quasars at 0.2 from the Quasar Feedback Survey (L > ), sel…
Obscuration beyond the nucleus: infrared quasars can be buried in extreme compact starbursts
Carolina Andonie, David M. Alexander, Claire Greenwell +14
In the standard quasar model, the accretion disk obscuration is due to the canonical dusty torus. Here, we argue that a substantial part of the quasar obscuration can come from the…
SUPER V. ALMA continuum observations of z~2 AGN and the elusive evidence of outflows influencing star formation
I. Lamperti, C. M. Harrison, V. Mainieri +24
We study the impact of AGN ionised outflows on star formation in high-redshift AGN hosts, by combining NIR IFS observations, mapping the H emission and [OIII] outflows, with mat…
The Quasar Feedback Survey: Discovering hidden Radio-AGN and their connection to the host galaxy ionised gas
M. E. Jarvis, C. M. Harrison, V. Mainieri +18
We present the first results from the Quasar Feedback Survey, a sample of 42 z<0.2, [O III] luminous AGN (L[O III]>10^42.1 ergs/s) with moderate radio luminosities (i.e. L(1.4GHz)>…
High molecular gas content and star formation rates in local galaxies that host quasars, outflows and jets
M. E. Jarvis, C. M. Harrison, V. Mainieri +11
We use a sample of powerful z~0.1 type 2 quasars ('obscured'; log[L(AGN)/erg/s]>~45), which host kiloparsec-scale ionized outflows and jets, to identify possible signatures of AGN…
