Title
What is Nature Astronomy and how do I get published in it?
Abstract
Nature Astronomy, launched in January 2017, is a new research journal
published by Springer Nature. Sitting alongside our sister journal
Nature, we aim to publish high impact research in the fields of
astronomy, astrophysics and planetary science. In this talk I will cover
the motivation and scope of the journal, the types of manuscripts we
publish, and what we look for in papers. I will also cover common
pitfalls of writing and submitting papers and I will share hints and
tips on how to maximize the impact of your paper, from writing an
engaging but informative title and a properly contextualized but concise
abstract, to structuring your paper in a way that your results are
communicated succinctly.

Title
In search of magnetic fields in galaxies with the flying telescope SOFIA
Abstract
Galaxies are known to be composed by stars, their remnants, interstellar
gas, dust and dark matter. Some galaxies host massive regions of star
formation and/or active super massive black holes on their cores,
commonly known as starburst galaxies and active galactic nuclei (AGN),
respectively. The activity produced by massive star formations and
energy released by accretion onto a supper massive black hole are
typical subjects of study to understand how stars form, how galaxies
evolve, and find relationships between them and their host galaxies.
Dust is an ubiquitous feature in both star formation regions and AGN.
Dust absorbs radiation at all wavelengths and re-emit it in the
infrared, peaking at ~100 microns for star formation and ~30 microns for
AGN. In both cases, gravitational forces are present, although magnetic
field have been proven to be key in the formation of stars as well as in
the dusty outflows of AGN. However, magnetic field are notoriously
difficult to observe. Polarimetric techniques provide a crucial approach
to characterize magnetic fields in these astrophysical environments.
The Stratospheric Observatory For Infrared Astronomy (SOFIA), with its
newest instrument HAWC+, has opened a new window to explore the role of
magnetic fields in starburst galaxies and AGN in the range of 50-300
microns. SOFIA has a 2.5-m telescope onboard a Boeing 747 flying at
45,000ft, which avoids ~95% of the water vapor in the atmosphere. We
here present newly obtained 50-200 microns imaging polarimetric
observations of a starburst, M82, and an AGN, NGC 1068. In both cases,
we have found a large-scale magnetic field structure dominated by star
formation regions in M82, and by a galactic magnetic field in NGC 1068.
We will also present the first 50-100 microns imaging polarimetric
observations of a radio-loud AGN, Cygnus A. We have found a highly
polarized (~10%) core dominated by dust emission in the 10-100 microns
wavelength range, while the mm wavelength range is dominated by
synchrotron emission.
