Star formation in AGN hosts in GOODS-N

L. Shao, D. Lutz, R. Nordon +40

Sensitive Herschel far-infrared observations can break degeneracies that were inherent to previous studies of star formation in high-z AGN hosts. Combining PACS 100 and 160um obser…

The Photodetector Array Camera and Spectrometer (PACS) on the Herschel Space Observatory

A. Poglitsch, C. Waelkens, N. Geis +80

The Photodetector Array Camera and Spectrometer (PACS) is one of the three science instruments on ESA's far infrared and submillimetre observatory. It employs two Ge:Ga photoconduc…

Star Formation in M51 Triggered by Galaxy Interaction

T. Nikola, N. Geis, F. Herrmann +4

We have mapped the inner 360'' regions of M51 in the 158micron [CII] line at 55'' spatial resolution using the Far-infrared Imaging Fabry-Perot Interferometer (FIFI) on the Kuiper…

Full disc [CII] mapping of nearby star-forming galaxies: SOFIA FIFI/LS observations of NGC 3627, NGC 4321, and NGC 6946

I. Kovačić, A. T. Barnes, F. Bigiel +20

As a major cooling line of interstellar gas, the far-infrared 158 μm line from singly ionised carbon [CII] is an important tracer of various components of the interstellar medium…

The effect of the high-pass filter data reduction technique on the Herschel PACS Photometer PSF and noise

P. Popesso, B. Magnelli, S. Buttiglione +36

We investigate the effect of the "high-pass filter" data reduction technique on the Herschel PACS PSF and noise of the PACS maps at the 70, 100 and 160 um bands and in medium and f…

CII Emission From NGC 4038/39 (The Antennae)

T. Nikola, R. Genzel, F. Herrmann +5

We present observations of NGC 4038/39 in the [CII] 158 micron fine structure line taken with the MPE/UCB Far-infrared Imaging Fabry-Perot Interferometer (FIFI) on the KAO with 55"…

The effects of star formation on the low-metallicity ISM: NGC4214 mapped with Herschel/PACS spectroscopy

D. Cormier, S. C. Madden, S. Hony +12

We present Herschel/PACS spectroscopic maps of the dwarf galaxy NC4214 observed in 6 far infrared fine-structure lines: [C II] 158mu, [O III] 88mu, [O I] 63mu, [O I] 146mu, [N II]…

SOFIA/FIFI-LS Full-disk [CII] Mapping and CO-dark Molecular Gas across the Nearby Spiral Galaxy NGC 6946

F. Bigiel, I. de Looze, A. Krabbe +17

We present SOFIA/FIFI-LS observations of the [CII] 158m cooling line across the nearby spiral galaxy NGC 6946. We combine these with UV, IR, CO, and H I data to compare [CII] e…

Realizing 3D Spectral Imaging in the Far-Infrared: FIFI LS

L. W. Looney, N. Geis, R. Genzel +6

We present a progress report on the design and construction of the Field-Imaging Far-Infrared Line Spectrometer (FIFI LS) for the SOFIA airborne observatory. The design of the inst…

16 x 25 Ge:Ga Detector Arrays for FIFI LS

D. Rosenthal, J. W. Beeman, N. Geis +5

We are developing two-dimensional 16 x 25 pixel detector arrays of both unstressed and stressed Ge:Ga photoconductive detectors for far-infrared astronomy from SOFIA. The arrays, b…
