Near- to Far-Infrared Spectral Energy Distribution Analysis of Interacting Galaxies in Hickson Compact Groups 56 and Stephan's Quintet (HCG 92)
Ayato Ikeuchi, Itsuki Sakon, Takashi Onaka +2
We investigate star formation activity in galaxies belonging to two Hickson Compact Groups (HCGs), HCG 56 and HCG 92 (Stephan's Quintet), both of which show clear evidence of inter…
Investigation of the Origin of the Anomalous Microwave Emission in Lambda Orionis
Aaron C. Bell, Takashi Onaka, Frédéric Galliano +5
The anomalous microwave emission (AME) still lacks a conclusive explanation. This excess of emission, roughly between 10 and 50 GHz, tends to defy attempts to explain it as synchro…
Radiative and mechanical feedback into the molecular gas in the Large Magellanic Cloud. II. 30 Doradus
Min-Young Lee, Suzanne Madden, Franck Le Petit +6
With an aim of probing the physical conditions and excitation mechanisms of warm molecular gas in individual star-forming regions, we performed Herschel SPIRE FTS observations of 3…
A look at possible microwave dust emission via AKARI infrared all-sky surveys
Aaron C. Bell, Takashi Onaka, Yasuo Doi +5
The anomalous microwave emission (AME) still lacks a conclusive explanation. This excess of emission, roughly between 10 and 50 GHz, correlates spatially with interstellar dust, pr…
Constraining physical conditions for the PDR of Trumpler 14 in the Carina Nebula
Ronin Wu, Emeric Bron, Takashi Onaka +5
We investigate the physical conditions of the CO gas near the young star cluster, Trumpler 14 of the Carina Nebula. The observations presented in this work are taken with the Fouri…
Evolution of the Unidentified Infrared Bands in the Nucleus of the Starburst Galaxy NGC 1097
Ronin Wu, Frédéric Galliano, Takashi Onaka
We present the analysis of the Unidentified Infrared Bands (UIB) in the starburst galaxy NGC 1097. We have combined spectral maps observed with the AKARI/IRC and Spitzer/IRS instru…
Near- to mid-Infrared Observations of Galaxy Mergers: NGC2782 and NGC7727
Takashi Onaka, Tomohiko Nakamura, Itsuki Sakon +5
We present the results of near- to mid-infrared (NIR to MIR) imaging and NIR spectroscopic observations of two galaxy mergers, NGC 2782 (Arp 215) and NGC 7727 (Arp 222), with the I…
SPICA and the Chemical Evolution of Galaxies: The Rise of Metals and Dust
J. A. Fernández-Ontiveros, L. Armus, M. Baes +33
The physical processes driving the chemical evolution of galaxies in the last cannot be understood without directly probing the dust-obscured phase of star-for…
Probing the cold and warm molecular gas in the Whirlpool Galaxy: Herschel SPIRE-FTS Observations of the central region of M51 (NGC 5194)
M. R. P. Schirm, C. D. Wilson, J. Kamenetzky +12
We present Herschel SPIRE-FTS intermediate-sampled mapping observations of the central ~8 kpc (~150") of M51, with a spatial resolution of 40". We detect 4 12CO transitions (J=4-3…
Disentangling the ISM phases of the dwarf galaxy NGC 4214 using [CII] SOFIA/GREAT observations
Katja Fahrion, Diane Cormier, Frank Bigiel +9
The [CII] 158 um fine structure line is one of the dominant cooling lines in the interstellar medium (ISM) and is an important tracer of star formation. Recent velocity-resolved st…
Radiative and mechanical feedback into the molecular gas in the Large Magellanic Cloud. I. N159W
Min-Young Lee, Suzanne Madden, Vianney Lebouteiller +25
We present Herschel SPIRE Fourier Transform Spectrometer (FTS) observations of N159W, an active star-forming region in the Large Magellanic Cloud (LMC). In our observations, a numb…
A milestone toward understanding PDR properties in the extreme environment of LMC-30Dor
M. Chevance, S. C. Madden, V. Lebouteiller +11
More complete knowledge of galaxy evolution requires understanding the process of star formation and interaction between the interstellar radiation field and the interstellar mediu…
Spatially resolved physical conditions of molecular gas and potential star formation tracers in M83, revealed by the Herschel SPIRE FTS
Ronin Wu, Suzanne Madden, Frédéric Galliano +19
Since the launch of the Herschel Space Observatory, our understanding about the photo-dissociation regions (PDR) has taken a step forward. In the bandwidth of the Fourier Transform…
The molecular gas reservoir of 6 low-metallicity galaxies from the Herschel Dwarf Galaxy Survey: A ground-based follow-up survey of CO(1-0), CO(2-1), and CO(3-2)
D. Cormier, S. C. Madden, V. Lebouteiller +14
We aim to quantify the molecular gas reservoir in a subset of 6 low-metallicity galaxies from the Herschel Dwarf Galaxy Survey with newly acquired CO data, and link this reservoir…
Herschel SPIRE-FTS Observations of Excited CO and [CI] in the Antennae (NGC 4038/39): Warm and Cold Molecular Gas
Maximilien R. P. Schirm, Christine D. Wilson, Tara J. Parkin +14
We present Herschel SPIRE-FTS observations of the Antennae (NGC 4038/39), a well studied, nearby ( Mpc) ongoing merger between two gas rich spiral galaxies. We detect 5 CO tran…
