High resolution (0."037-0."13 [10-35 pc]) e-MERLIN ( cm) and (0."024 [6.5 pc]) ALMA ( mm) observations have been used to image OH (hydroxyl) and HCO (formald…
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
Compact obscured nuclei (CONs) are relatively common in the centers of local (U)LIRGs, yet their nature remains unknown. Both AGN activity and extreme nuclear starbursts have been…
Long-period maser-bearing Miras in the Galactic center: period-luminosity relations and extinction estimates
M. O. Lewis, R. Bhattacharya, L. O. Sjouwerman +5
We establish a sample of 370 Mira variables that are likely near the Galactic center (GC). The sources have been selected from the OGLE and BAaDE surveys based on their sky coordin…
SUNRISE: The rich molecular inventory of high-redshift dusty galaxies revealed by broadband spectral line surveys
Chentao Yang, Alain Omont, Sergio Martín +21
Understanding the nature of high- dusty galaxies requires a comprehensive view of their ISM and molecular complexity. However, the molecular ISM at high- is commonly studied…

Chentao Yang, Susanne Aalto, Sabine König +7
We here present 0.02-0.04'' resolution ALMA observation of the compact obscured nucleus (CON) of IRAS17578-0400. A dusty torus within the nucleus, approximately 4 pc in radius, has…
The Opaque Heart of the Galaxy IC 860: Analogous Protostellar, Kinematics, Morphology, and Chemistry
M. D. Gorski, S. Aalto, S. König +7
Compact Obscured Nuclei (CONs) account for a significant fraction of the population of luminous and ultraluminous infrared galaxies (LIRGs and ULIRGs). These galaxy nuclei are comp…
The Morpho-Kinematic Architecture of Super Star Clusters in the Center of NGC253
Rebecca C. Levy, Alberto D. Bolatto, Adam K. Leroy +9
The center of the nearby galaxy NGC\,253 hosts a population of more than a dozen super star clusters (SSCs) which are still in the process of forming. The majority of the star form…
Methanol masers in NGC 253 with ALCHEMI
P. K. Humire, C. Henkel, A. Hernández-Gómez +23
Context: Methanol masers of Class I (collisionally-pumped) and Class II (radiatively-pumped) have been studied in great detail in our Galaxy in a variety of astrophysical environme…
ALMA Imaging of a Galactic Molecular Outflow in NGC4945
Alberto D. Bolatto, Adam K. Leroy, Rebecca C. Levy +10
We present the ALMA detection of molecular outflowing gas in the central regions of NGC4945, one of the nearest starbursts and also one of the nearest hosts of an active galactic n…
Discovery of Methanimine Megamasers Toward Compact Obscured Galaxy Nuclei
Mark Gorski, Susanne Aalto, Jeffrey Mangum +8
We present the first search for the 5.29 GHz methanimine() transition toward a sample of galaxy nuclei. We target seven galaxies that host Compact…
Clustered Star Formation in the center of NGC 253 Contributes to Driving the Ionized Nuclear Wind
E. A. C. Mills, M. Gorski, K. L. Emig +12
We present new 3 mm observations of the ionized gas toward the nuclear starburst in the nearby (D ~ 3.5 Mpc) galaxy NGC 253. With ALMA, we detect emission from the H40-alpha and He…
CON-quest: Searching for the most obscured galaxy nuclei
N. Falstad, S. Aalto, S. König +28
Some luminous and ultraluminous infrared galaxies (LIRGs and ULIRGs) host extremely compact and dusty nuclei. The intense infrared radiation arising from warm dust in these sources…
Distances to Galactic X-ray Binaries with Gaia DR2
R. M. Arnason, H. Papei, P. Barmby +2
Precise and accurate measurements of distances to Galactic X-ray binaries (XRBs) reduce uncertainties in the determination of XRB physical parameters. We have cross-matched the XRB…
Outflows from Super Star Clusters in the Central Starburst of NGC253
Rebecca C. Levy, Alberto D. Bolatto, Adam K. Leroy +13
Young massive clusters play an important role in the evolution of their host galaxies, and feedback from the high-mass stars in these clusters can have profound effects on the surr…
