Two-dimensional multi-component photometric decomposition of CALIFA galaxies

J. Mendez-Abreu, T. Ruiz-Lara, L. Sanchez-Menguiano +20

We present a two-dimensional multi-component photometric decomposition of 404 galaxies from the CALIFA Data Release 3. They represent all possible galaxies with no clear signs of i…

Evidence of ongoing radial migration in NGC 6754: Azimuthal variations of the gas properties

L. Sánchez-Menguiano, S. F. Sánchez, D. Kawata +9

Understanding the nature of spiral structure in disk galaxies is one of the main, and still unsolved questions in galactic astronomy. However, theoretical works are proposing new t…

Stellar kinematics across the Hubble sequence in the CALIFA survey: General properties and aperture corrections

J. Falcón-Barroso, M. Lyubenova, G. van de Ven +32

We present the stellar kinematic maps of a large sample of galaxies from the integral-field spectroscopic survey CALIFA. The sample comprises 300 galaxies displaying a wide range o…

Size of the accretion disk in the gravitationally lensed quasar SDSS J1004+4112 from the statistics of microlensing magnifications

C. Fian, E. Mediavilla, A. Hanslmeier +4

We present eight monitoring seasons of the four brightest images of the gravitational lens SDSS J1004+4112 observed between December 2003 and October 2010. Using measured time dela…

Planck intermediate results. XLV. Radio spectra of northern extragalactic radio sources

Planck Collaboration, P. A. R. Ade, N. Aghanim +202

Continuum spectra covering centimetre to submillimetre wavelengths are presented for a northern sample of 104 extragalactic radio sources, mainly active galactic nuclei, based on f…

Dust Properties in HII Regions in M33

M. Relano, R. Kennicutt, U. Lisenfeld +11

The conversion of the IR emission into star formation rate can be strongly dependent on the physical properties of the dust, which are affected by the environmental conditions wher…

Observations of the Lensed Quasar Q2237+0305 with CanariCam at GTC

H. Vives-Arias, J. A. Munoz, C. S. Kochanek +2

We present new mid-IR observations of the quadruply lensed quasar Q2237+0305 taken with CanariCam on the Gran Telescopio Canarias. Mid-IR emission by hot dust, unlike the optical a…

The BaLROG project - II. Quantifying the influence of bars on the stellar populations of nearby galaxies

Marja K. Seidel, Jesús Falcón-Barroso, Inma Martínez-Valpuesta +4

We continue the exploration of the BaLROG (Bars in Low Redshift Optical Galaxies) sample: 16 large mosaics of barred galaxies observed with the integral field unit SAURON. We quant…

Effect of local and large-scale environments on nuclear activity and star formation

M. Argudo-Fernández, S. Shen, J. Sabater +3

Active galactic nuclei (AGN) is one of the main drivers for transition from star-forming disk to passive spheroidal galaxies. However, the role of large-scale environment versus on…

The multiphase starburst-driven galactic wind in NGC 5394

P. Martín-Fernández, J. Jiménez-Vicente, A. Zurita +2

We present a detailed study of the neutral and ionised gas phases in the galactic wind for the nearby starburst galaxy NGC 5394 based on new integral field spectroscopy obtained wi…

Molecular gas and star formation in the Tidal Dwarf Galaxy VCC 2062

U. Lisenfeld, J. Braine, P. A. Duc +5

The physical mechanisms driving star formation (SF) in galaxies are still not fully understood. Tidal dwarf galaxies (TDGs), made of gas ejected during galaxy interactions, seem to…

Shocked POststarburst Galaxy Survey II: The Molecular Gas Content and Properties of a Subset of SPOGs

Katherine Alatalo, Ute Lisenfeld, Lauranne Lanz +8

We present CO(1-0) observations of objects within the Shocked POststarburst Galaxy Survey taken with the Institut de Radioastronomie Millimetrique (IRAM) 30m single dish and the Co…

Towards universal hybrid star formation rate estimators

M. Boquien, R. Kennicutt, D. Calzetti +13

To compute the SFR of galaxies from the rest-frame UV it is essential to take into account the obscuration by dust. To do so, one of the most popular methods consists in combining…

Millimeter and Submillimeter Excess Emission in M33 revealed by Planck and LABOCA

I. Hermelo, M. Relaño, U. Lisenfeld +6

Previous studies have shown the existence of an excess of emission at submillimeter (submm) and millimeter (mm) wavelengths in the spectral energy distribution (SED) of many low-me…

Shape of the oxygen abundance profiles in CALIFA face-on spiral galaxies

L. Sánchez-Menguiano, S. F. Sánchez, I. Pérez +25

We measured the gas abundance profiles in a sample of 122 face-on spiral galaxies observed by the CALIFA survey and included all spaxels whose line emission was consistent with sta…
