Positive feedback, quenching and sequential super star cluster (SSC) formation in NGC 4945
Enrica Bellocchi, Jesús Martín-Pintado, Fernando Rico-Villas +2
We have used ALMA imaging (resolutions 0.1\arcsec-0.4\arcsec) of ground and vibrationally excited lines of HCN and HCN toward the nucleus of NGC 4945 to trace the protostellar…
On the thermal structure of the proto-Super Star Cluster 13 in NGC 253
F. Rico-Villas, E. González-Alfonso, J. Martín-Pintado +2
Using high angular resolution ALMA observations ( pc), we study the thermal structure and kinematics of the proto super star cluster in the cen…
Molecular precursors of the RNA-world in space: new nitriles in the G+0.693-0.027 molecular cloud
Víctor M. Rivilla, Izaskun Jiménez-Serra, Jesus Martín-Pintado +10
Nitriles play a key role as molecular precursors in prebiotic experiments based on the RNA-world scenario for the origin of life. These chemical compounds could have been partially…
Precursors of the RNA-world in space: Detection of ()-1,2-ethenediol in the interstellar medium, a key intermediate in sugar formation
Víctor M. Rivilla, Laura Colzi, Izaskun Jiménez-Serra +20
We present the first detection of ()-1,2-ethenediol, (CHOH), the enol form of glycolaldehyde, in the interstellar medium towards the G+0.693-0.027 molecular cloud located in…
Deuterium fractionation as a multi-phase component tracer in the Galactic Centre
L. Colzi, J. Martín-Pintado, V. M. Rivilla +6
The Central Molecular Zone (CMZ) contains most of the mass of our Galaxy but its star formation rate is one order of magnitude lower than in the Galactic disc. This is likely relat…
Negative and Positive Feedback from a Supernova Remnant with SHREC: A detailed Study of the Shocked Gas in IC443
G. Cosentino, I. Jiménez-Serra, J. C. Tan +20
Supernova remnants (SNRs) contribute to regulate the star formation efficiency and evolution of galaxies. As they expand into the interstellar medium (ISM), they transfer vast amou…
Probing the chemical complexity of amines in the ISM: detection of vinylamine (CHNH) and tentative detection of ethylamine (CHNH)
Shaoshan Zeng, Izaskun Jiménez-Serra, Víctor M. Rivilla +8
Amines, in particular primary amines (R-NH) are closely related to the primordial synthesis of amino acids since they share the same structural backbone. However, only limited…
First detection of CHNCO in the ISM and search of other isocyanates towards the G+0.693-0.027 molecular cloud
L. F. Rodríguez Almeida, V. M. Rivilla, I. Jiménez-Serra +9
Little is known about the chemistry of isocyanates (compounds with the functional group R-N=C=O) in the interstellar medium, as only four of them have been detected so far: isocyan…
Detection of the cyanomidyl radical (HNCN): a new interstellar species with the NCN backbone
V. M. Rivilla, I. Jiménez-Serra, J. García de la Concepción +9
We report here the first detection in the interstellar medium of the cyanomidyl radical (HNCN). Using the Yebes 40m and the IRAM 30m telescopes, we have targeted the doublets of th…
Discovery in space of ethanolamine, the simplest phospholipid head group
Víctor M. Rivilla, Izaskun Jiménez-Serra, Jesús Martín-Pintado +9
Cell membranes are a key element of life because they keep the genetic material and metabolic machinery together. All present cell membranes are made of phospholipids, yet the natu…
Thiols in the ISM: first detection of HC(O)SH and confirmation of CHSH
Lucas F. Rodríguez-Almeida, Izaskun Jiménez-Serra, Víctor M. Rivilla +8
The chemical compounds carrying the thiol group (-SH) have been considered essential in recent prebiotic studies regarding the polymerization of amino acids. We have searched for t…
A proto-pseudobulge in ESO 320-G030 fed by a massive molecular inflow driven by a nuclear bar
Eduardo González-Alfonso, Miguel Pereira-Santaella, Jacqueline Fischer +10
Galaxies with nuclear bars are believed to efficiently drive gas inward, generating a nuclear starburst and possibly an active galactic nucleus (AGN). We confirm this scenario for…
Prebiotic precursors of the primordial RNA world in space: Detection of NHOH
Víctor M. Rivilla, Jesús Martín-Pintado, Izaskun Jiménez-Serra +6
One of the proposed scenarios for the origin of life is the primordial RNA world, which considers that RNA molecules were likely responsible for the storage of genetic information…
Propargylimine in the laboratory and in space: millimetre-wave spectroscopy and first detection in the ISM
Luca Bizzocchi, Domenico Prudenzano, Victor M. Rivilla +10
Small imines containing up to three carbon atoms are present in the interstellar medium. As alkynyl compounds are abundant in this medium, propargylimine thus represents a promisin…
Spectral Line Identification and Modelling (SLIM) in the MAdrid Data CUBe Analysis (MADCUBA) package: An interactive software for data cube analysis
S. Martín, J. Martín-Pintado, C. Blanco-Sánchez +3
In this paper we present the detailed formalism at the core of the Spectral Line Identification and Modelling (SLIM) within the MAdrid Data CUBe Analysis (MADCUBA) package and thei…

Spectroscopic comparison between ultraluminous X-ray sources and magnetar bursts
J. J. E. Kajava, F. Rico-Villas
Nearby galaxies host ultra-luminous X-ray sources (ULXs), whose nature remains largely unknown. Until the discovery of the first ULX pulsar, M82 X-2, the mechanism powering the lar…
