The magnetic field in the central parsec by Glasse, A, Aitken, D, Roche, P

The magnetic field in the central parsec of the Galaxy by Roche, P, Lopes-Rodriguez, E, Telesco, C, Schoedel, R, Packham, C

“…We present a polarisation map of the warm dust emission from the minispiral in the central parsec of the Galactic centre. The observations were made at a wavelength of 12.5 μm with CanariCam mounted on the 10.4-m Gran Telescopio Canarias. …”

High resolution imaging of the magnetic field in the central parsec of the Galaxy by Roche, P, Lopez Rodriguez, E, Telesco, C, Schodel, R, Packham, C

MULTICOLOR, 8-13-MU-M MAPS OF THE CENTRAL PARSEC OF THE GALAXY by Smith, C, Aitken, D, Roche, P

Mid-infrared polarization studies of SgrA: a three-dimensional study of the central parsec by Aitken, D, Smith, C, Moore, T, Roche, P

“…It is shown that the physical conditions in the ionized filaments of the central parsec lead to a very uniform grain alignment that is directed along the local magnetic field. …”

Science of Active Galactic Nuclei with the GTC and CanariCam by Levenson, N, Packham, C, Herrero, A, Aretxaga, I, Colina, L, Santos, T, Elitzur, M, Mason, R, Perlman, E, Radomski, J, Roche, P, Espinosa, J, Young, S, Telesco, C

“…Current work demonstrates that the hot dust immediately associated with the AGN, which blocks direct views of the AGN from some lines of sight, is con.ned to small (parsec) scales. Thus, high spatial resolution is essential to probe the "torus" of unified AGN models separate from the host galaxy. …”

Mid-infrared sub-arcsecond spectroscopy of active galaxy nuclei by Roche, P

“…Several nearby active galaxies show evidence of resolved circumnuclear dusty structures with sizes of 10s of parsecs. The silicate absorption profile towards the most heavily obscured nuclei are narrower than those in the galaxies with tau((9.7 mu m)) < 3, possibly reflecting larger average grain sizes in the latter resulting from destruction of the smallest grains by the AGN.…”

Nuclear molecular outflow in the Seyfert galaxy NGC 3227 by Alonso Herrero, A, García-Burillo, S, Pereira-Santaella, M, Davies, R, Combes, F, Vestergaard, M, Raimundo, S, Bunker, A, Díaz-Santos, T, Gandhi, P, García-Bernete, I, Hicks, E, Hönig, S, Hunt, L, Imanishi, M, Izumi, T, Levenson, N, Maciejewski1, W, Packham, C, Ramos Almeida, C, Ricci, C, Rigopoulou, D, Roche, P, Rosario, D, Schartmann, M, Usero, A, Ward, M

“…On large scales, the cold molecular gas shows circular motions as well as streaming motions on scales of a few hundred parsecs that are associated with a large-scale bar. …”

Silicate absorption in heavily obscured galaxy nuclei by Roche, P, Packham, C, Aitken, D, Mason, R

“…In NGC 5506, the depth of the silicate absorption increases from north to south across the nucleus, suggestive of a dusty structure on scales of tens of parsecs. We discuss the profile of the silicate absorption band towards galaxy nuclei and the relationship between the 9.7-μm silicate and 3.4-μm hydrocarbon absorption bands. © 2007 RAS.…”

Mid-infrared, spatially resolved spectroscopy of the nucleus of the Circinus galaxy by Roche, P, Packham, C, Telesco, C, Radomski, J, Alonso-Hererro, A, Aitken, D, Colina, L, Perlman, E

“…These data are interpreted in terms of an inclined disc-like structure around the nucleus extending over tens of parsecs and possibly related to the inner disc found from observations of water masers by Greenhill et al. © 2006 RAS.…”

The complex evolutionary paths of local infrared bright galaxies: a high-angular resolution mid-infrared view by Roche, P, Alonso-Herrero, A, Poulton, R, Hernán-Caballero, A, Aretxaga, I, Martínez-Paredes, M, Ramos Almeida, C, Pereira-Santaella, M, Díaz-Santos, T, Levenson, N, Packham, C, Colina, L, Esquej, P, González-Martín, O, Ichikawa, K, Imanishi, M, Rodríguez Espinosa, J, Telesco, C

“…We use high-angular resolution (∼0.3–0.4 arcsec∼few hundred parsecs) 8–13µm ground-based spectroscopy to disentangle the active galactic nuclei (AGN) id-IR properties from those of star formation. …”
