Introduction

This annual report has been edited during complicated times of the corona virus epidemy but this should not distract us from looking back on 2019 which was thoroughly positive for IRAM although at the same time not without new challenges.

The year 2019 was rich of important events and scientific results. In fact, NOEMA and powerful new instruments at the 30-meter telescope produce so much high-quality data that we are clearly entering in a new phase of how science is done with the IRAM facilities. At the same time IRAM users have started now to fully embrace the possibilities which are available through large programs and their significant impact on all fields of millimetre wave astronomy.

The required infrastructure to treat the very important data flows which are generated through large programs and the ever-increasing performance of the IRAM instruments is now reaching a mature status with the direct optical fibre connections from the observatories to the Granada office and the Grenoble headquarter, the upgraded infrastructure in data storage and computing and finally the very significant advances in data reduction software.

IRAM is now half way through the second NOEMA phase with Antenna 11 foreseen to be integrated into the array in summer 2020 and the baseline extension started. This has been possible not to the least through a new strategic partnership with the University of Wisconsin Madison which was concluded in 2019. IRAM has also continued to seek collaborations on instrumentation with other leading laboratories and in particular with very fruitful exchanges with the SAO/SMA and NAOJ. 5

Meanwhile no time has been lost in the labs to develop and prototype the next technological level of instrumentation. Dual band receiver and water vapour metrology prototypes have been commissioned and the next level of bandwidth enhancement and multibeam receiver technology is under development.

Obviously, the most visible event has been the publication of the ﬁrst Event Horizon Telescope collaboration result, the imaging of the M87 black hole shadow. With its performance and geographic position, the IRAM 30-meter telescope was absolutely essential in taking this epoch-marking picture, for which the collaboration was awarded the Breakthrough prize 2020. Intense development eﬀorts are underway to prepare phasing of the NOEMA antennas to support future EHT runs with NOEMA’s outstanding sensitivity.

The basis of IRAM’s success remains the stable and constructive partnership among its stakeholders and the competent and highly motivated staﬀ which has been joined by many new colleagues from all over the world during the year. For a director this is one of the most unambiguous signs that the ship is on good track.

With best regards

However, the authors AA, 621, A76. In an effort to improve the understanding of the formation of accretion disks and multiple systems during the protostellar collapse, the role of Class 0 jets and outflows in angular momentum extraction, and the kinematics and structure of the inner protostellar environment, Anaëlle Maury (AIM/CEA/CNRS/Paris) and collaborators have been working on CALYPSO (Continuum And Lines in Young ProtoStellar Objects), an IRAM Large Program. In this framework, sub- arcsecond observations using the former Plateau de Bure interferometer were obtained at 94 and 231 GHz for a sample of 16 solar-type Class 0 protostars.

To identify disk-like structures embedded at small scales in the protostellar envelopes, Maury and collaborators modeled the dust continuum emission visibility proﬁles using Plummer-like envelope models and envelope models that include additional Gaussian disk-like components. Their analysis showed that in the CALYPSO sample about 70% of the Class 0 protostars are better reproduced by models that include a disk-like dust continuum component but that less than 25% are resolved at radii >60 au. Also, according to the study, ≤57% ± 10% of the CALYPSO sources underwent fragmentation into multiple systems over scales of 100–5000 au, which generally agrees with the multiplicity properties of Class I protostars at similar scales.

In particular, the amount of of 0.09 sources, and five sources at 4.4 > S/N ≥ 3.7 dust that could have reasonably been formed in among which 1.65 are possibly false detections. Five primordial galaxies within the first few hundred of the sources have counterparts in (sub)millimeter million years after the Big Bang is still heavily debated. catalogs available in COSMOS. Their redshifts suggest Despite some limitations, work over the past two that all but one lie above redshift ~3. The four galaxies decades has led to the discovery of considerable at redshift ~3.9 have SFRs ~400–1200 M⊙/yr and dust populations of dusty star-forming galaxies (DSFGs) at masses of ~109.5 M⊙. They thereby provide a relatively high redshifts through deep-field survey campaigns complete selection (~66%) of the most luminous 12.6 at (sub)millimeter wavelengths. However, most of (LIR > 10 L⊙) and highest-redshift (z > 3) galaxies these surveys do not probe sufficiently the long detected within the survey area by AzTEC at 1.1 mm. rest-frame wavelengths to yield accurate dust mass estimates. According to the researchers their GISMO 2-mm survey, combined with the confusion-limited In an attempt to address this question, Benjamin GISMO 2-mm deep field in GOODS-N has Magnelli (Argelander Institut/Bonn) and collaborators unambiguously demonstrated the advantage of undertook a pioneering survey in the largely long-wavelength surveys for studying the rare, unexplored 2 mm window using the Goddard-IRAM massive, high-redshift, highly star-forming galaxies.

RADIATIVE FEEDBACK FROM MASSIVE STARS IN OMC1

Once a massive O-type star is formed, the energy and To shed new light on the role of massive stars and momentum injected by photoionization, radiation quantify stellar feedback processes at different pressure, and stellar winds ionize and erode the natal spatial scales, a team of astronomers led by Javier molecular cloud, creating H II regions and blowing Goicoechea (CSIC/Madrid) used Herschel/HIFI to expanding bubbles.

These effects are not limited CO (J = 10–9), HCO+ (J = 6–5), HCN (J = 6–5), to the close vicinity of massive stars, and they can CH (N, J = 1, 3/2–1, 1/2), C18O (J = 2–1), determine the physical conditions and the chemistry HCO+ (J = 3–2), their investigations established that of the gas on scales of several parsec. by heating, compressing, and photoevaporating the cloud edge, the intense FUV radiation field emanating from massive stars in the Trapezium cluster triggers the formation of specific reactive molecules such as CH+. The researchers show that the CH+ (J = 1–0) emission correlates spatially with the flux of FUV photons impinging the cloud, the extended infrared emission from vibrationally excited

The FUV radiation ﬁeld is found to be so strong that it drives the heating and chemistry of an extended component of 100–150 K warm molecular gas up to parsec-scale distances from the massive stars. This is seen in particular from the larger extent of the CO (J = 10–9) emission compared to that of C18O (J = 2–1).

The authors conclude that similar processes must take place in other clusters hosting more numerous and more massive stars. Annual Report 2019 11

+ ENHANCED NFRACTIONATION IN N2H : THE CASE OF IRAS 05385+3543

The origin of the Solar System is a highly debated topic. Understanding the origin of the molecules in diﬀerent Solar System bodies is important to have information on the protosolar nebula (PSN) from which our Sun was born. In particular, it is not clear if molecules in pristine Solar System bodies, like comets or asteroids, were inherited from the cold and dense PSN or if they are the result of chemical processing within the solar protoplanetary disc. One of the most used approaches to the disentangling of these two development paths is the measurement of the 14N/15N ratio using diﬀerent molecules.

Laura Colzi (University Firenze/INAF) and collaborators from MPE/Garching used the NOEMA interferometer + 15 + to observe the emission of N2H , and the NNH and N15NH+ isotopologues towards the high-mass star-forming protocluster IRAS 05358+3543. The + N2H dense gas emission consists of three main cores, two of which are offset with respect to the 3.2 mm continuum sources, probably because of star + formation activity that causes the N2H destruction by CO desorption from grain mantles. They find 14N/15N ratios between ~100 and ~220, somewhat lower or equal to those observed with single-dish observations towards the same source. This indicates the possibility that the 15N enrichment in star-forming regions is a local effect. Since N-fractionation changes across the studied region, the researchers suggest that it is regulated by local environmental effects.

This study shows that the lower values of ~100 towards the protocluster cores are similar to some values measured in other protoplanetary discs, and also to the low values measured in the pristine Solar System bodies.

The column density of CN is estimated to 7.6×1012 cm−2 and the relative CN/CO abundance to 2.6 10−3. This ratio is relatively high for dense clouds, by 1 or 2 orders of magnitude, but not necessarily for more diffuse clouds for which some models predict abundances 100 times higher.

In the near future, the increased sensitivity of NOEMA, ALMA and large blind surveys with SKA precursors will make it possible to discover further weak absorbing systems, which has been impossible so far. According to the authors of the study this is the ﬁrst ever millimeter absorber without lensing potential.

EMIR was used during almost 79% of the observing hours, while HERA was used for 2% of the time, and NIKA2 usage has increased to 20%. During more than 42% of the EMIR time, its 3 mm band E090 was used in single-band mode. The 3 mm band was used an additional 37% in dual-band mode, i.e. together with the 2 or 1 mm bands E150 and E230, respectively. The 1 mm band E230 was used during 36% of the Annual Report 2019 19

OBSERVATORY OPERATION

In 2019, more than 69% of the total available time was allocated to scientiﬁc observations with either EMIR, HERA or NIKA2. This fraction is more than 10 percent larger than the previous year and actually is the largest in last ﬁve years. This is mostly due to a reduction of time losses due to poor weather conditions (around 23% versus 32% in 2018). On the other hand, the time fraction spent in maintenance and technical activities has been further reduced to some 7%. Finally, the time lost due to technical problems remains extremely low, less than 1%.

As for previous years, the main activities carried out by the telescope group include maintenance of the observatory systems and equipment, help in Usage of the total time at the 30-meter telescope in 2019. troubleshooting of operation issues and repair of faulty equipment.

FIBER OPTIC CONNECTION TO NOEMA

The Computer Group has set up a high speed optical connection between the IRAM headquarter and the NOEMA observatory in April 2019. To keep the control of this critical link over the time, IRAM has signed a 23-years leasing for a black fiber optic so that the Computer Group can install its own equipment to illuminate the fibers. The illumination devices are manufactured by Ekinops and allow a direct connection, without repeaters on the 160 km length fiber. It is possible because the fiber is continuous without intermediate connectors (only welding) with less than 41 dB of attenuation (this value includes the fiber aging budget over 25 years). The measured attenuation is only 37 dB, so there is a very comfortable margin.

The Ekinops devices support multiplexing, so as a ﬁrst step, 2 x 10 Gbps channels have been enabled. With Detail of the Ekinops optical rack. 1000 times more network bandwidth than before, this new link clears the distance between both sites. It is a game changer for IRAM operations: staﬀ can work in real-time regardless the activities or the physical location. If even more bandwidth is needed in the future, it will be possible to enable other channels on the Ekinops racks, or replace them with faster models (100, 200 or 400 Gbps).

Another benefit of the new optical connection is and are stored on a FreeNAS storage server. Then that the overall architecture can be simplified to the data are replicated in real-time on the other have symmetric datacenters at the headquarter site to protect them. Nevertheless, as before, both and at the NOEMA observatory.

IRAM operates two observatories – the 30-meter Telescope on Pico Veleta in the Sierra Nevada and NOEMA, an interferometer of ten 15-meter antennas on the Plateau de Bure in the French Alps.

IRAM was founded in 1979 by two national research organizations: the CNRS and the Max-Planck-Gesellschaft – the Spanish Instituto Geográ co Nacional, initially an associate member, became a full member in 1990.

The technical and scienti c sta of IRAM develops instrumentation and software for the speci c needs of millimeter radioastronomy and for the bene t of the international astronomical community.

IRAM scientists conduct forefront research in several domains of astrophysics, from nearby star-forming regions to objects at cosmological distances.
