J. H. Knapen, L. M. Mazzuca, T. Boeker +4
Context: The morphology of massive star formation in the central regions of galaxies is an important tracer of the dynamical processes that govern the evolution of disk, bulge, and…
Extreme Starbursts in the Local Universe
R. M. Gonzalez Delgado, J. Rodriguez Zaurin, E. Perez +44
The "Extreme starbursts in the local universe" workshop was held at the Insituto de Astrofisica de Andalucia in Granada, Spain on 21-25 June 2010. Bearing in mind the advent of a n…
Clumpy star formation and an obscured nuclear starburst in the luminous dusty z=4 galaxy GN20 seen by MIRI/JWST
A. Bik, J. Ãlvarez-Márquez, L. Colina +28
Dusty star-forming galaxies emit most of their light at far-IR to mm wavelengths as their star formation is highly obscured. Far-IR and mm observations have revealed their dust, ne…
Extranuclear Halpha-emitting complexes in low-z (U)LIRGs: Precursors of tidal dwarf galaxies?
D. Miralles-Caballero, L. Colina, S. Arribas
(Abridged)This paper characterizes the physical and kinematic properties of external massive star-forming regions in a sample of (U)LIRGs. We use high angular resolution ACS images…
JOYS: Disentangling the warm and cold material in the high-mass IRAS 23385+6053 cluster
C. Gieser, H. Beuther, E. F. van Dishoeck +20
(abridged) We study and compare the warm (>100 K) and cold (<100 K) material toward the high-mass star-forming region IRAS 23385+6053 (IRAS 23385 hereafter) combining high angular…
Insight into the Starburst Nature of Galaxy GN-z11 with JWST MIRI Spectroscopy
J. Ãlvarez-Márquez, A. Crespo Gómez, L. Colina +21
This paper presents a deep MIRI/JWST medium resolution spectroscopy (MRS) covering the rest-frame optical spectrum of the GN-z11 galaxy. The [OIII]5008 and H emission lines are…
INTEGRAL Spectroscopy of IRAS 17208-0014: Implications for the Evolutionary Scenarios of Ultraluminous Infrared Galaxies
S. Arribas, L. Colina
New integral field optical fiber spectroscopy obtained with the INTEGRAL system, together with archival {\it {\it HST}} WFPC2 and NICMOS images, have been used to investigate the u…
JOYS: JWST Observations of Young protoStars: Outflows and accretion in the high-mass star-forming region IRAS23385+605
H. Beuther, E. F. van Dishoeck, L. Tychoniec +21
Aims: The JWST program JOYS (JWST Observations of Young protoStars) aims at characterizing the physical and chemical properties of young high- and low-mass star-forming regions, in…
Nuclear Bar, Star Formation and Gas Fueling in the Active Galaxy NGC 4303
L. Colina, K. Wada
A combination of Hubble Space Telescope (HST) WFPC2 and NICMOS images are used to investigate the gas/dust and stellar structure inside the central 300 pc of the nearby active gala…
Duality in spatially resolved star-formation relations in local LIRGs
M. Sánchez-GarcÃa, M. Pereira-Santaella, S. GarcÃa-Burillo +10
We analyse the star formation (SF) relations in a sample of 16 nearby luminous infrared galaxies (LIRGs) with more than 2800 regions defined on scales of 90 to 500 pc. We used ALMA…
The emergence of the Star Formation Main Sequence with redshift unfolded by JWST
P. Rinaldi, R. Navarro-Carrera, K. I. Caputi +13
We investigate the correlation between stellar mass (M*) and star formation rate (SFR) across the stellar mass range log10(M*/Msun)~6-11. We consider almost 50,000 star-forming gal…
HST NICMOS and WFPC2 Imaging of Ultraluminous Galaxies
K. D. Borne, H. Bushouse, L. Colina +6
HST is used to study the power sources and the interaction-induced tidal disturbances within the most luminous galaxies in the local universe -- the Ultra-Luminous IR Galaxies (ULI…
The PUMA project. III. Incidence and properties of ionised gas disks in ULIRGs, associated velocity dispersion and its dependence on starburstiness
M. Perna, S. Arribas, L. Colina +11
A classical scenario suggests that ULIRGs transform colliding spiral galaxies into a spheroid dominated early-type galaxy. Recent high-resolution simulations have instead shown tha…
