Context. Outflows provide indirect means to gain insight into diverse star formation-associated phenomena. At the level of individual protostellar cores, both outflows and the intrinsic core properties can be used to study the mass accretion/ejection process of heavily embedded protostellar sources. Aims. The main objective of the paper is to study the overall outflow distribution and its association with the young population of the Serpens Core cluster. In addition, the paper addresses the… 
Feedback of atomic jets from embedded protostars in NGC 1333
Context. The feedback of star formation to the parent cloud is conventionally examined through the study of molecular outflows. Little is known, however, about the effect that atomic ejecta tracing
Characterizing Magnetic Field Morphologies in Three Serpens Protostellar Cores with ALMA
With the aim of characterizing the dynamical processes involved in the formation of young protostars, we present high angular resolution ALMA dust polarization observations of the Class 0
Outflow forces in intermediate mass star formation
Context. Protostars of intermediate mass provide a bridge between theories of low- and high-mass star formation. Molecular outflows emerging from such sources can be used to determine the influence
High-pressure, low-abundance water in bipolar outflows - Results from a Herschel-WISH survey
Context. Water is a potential tracer of outflow activity because it is heavily depleted in cold ambient gas and is copiously produced in shocks. Aims. We present a survey of the water emission in a
Chemical and kinematic structure of extremely high-velocity molecular jets in the Serpens Main star-forming region
Context. Outflows are one of the first signposts of ongoing star formation. The fastest molecular component of protostellar outflows, extremely high-velocity (EHV) molecular jets, are still puzzling
Water in star-forming regions with Herschel (WISH). II. Evolution of 557 GHz 110-101 emission in low-mass protostars
Context. Water is a key tracer of dynamics and chemistry in low-mass star-forming regions, but spectrally resolved observations have so far been limited in sensitivity and angular resolution, and
Atomic jet from SMM1 (FIRS1) in Serpens uncovers protobinary companion
We report on the detection of an atomic jet associated with the protostellar source SMM1 (FIRS1) in Serpens. The jet is revealed in [FeII] and [NeII] line maps observed with Spitzer/IRS, and further
The Circumstellar Environment around the Embedded Protostar EC 53
EC53 is an embedded protostar with quasi-periodic emission in the near-IR and sub-mm. We use ALMA high-resolution observations of continuum and molecular line emission to describe the circumstellar
The JCMT Transient Survey: Detection of sub-mm variability in a Class I protostar EC 53 in Serpens Main
During the protostellar phase of stellar evolution, accretion onto the star is expected to be variable, but this suspected variability has been difficult to detect because protostars are deeply
Investigating Particle Acceleration in Protostellar Jets: The Triple Radio Continuum Source in Serpens
While most protostellar jets present free-free emission at radio wavelengths, synchrotron emission has been also proposed to be present in a handful of these objects. The presence of non-thermal


A burst of outflows from the Serpens cloud core: wide-field submillimetre continuum, CO J=2–1 and optical observations
Wide-field mapping of Serpens in submillimetre continuum emission and CO J=2–1 line emission is here complemented by optical imaging in [S ii] λλ6716, 6731 line emission. Analysis of the 450- and
An unbiased search for the signatures of protostars in the ρ Ophiuchi molecular cloud , II. Millimetre continuum observations
The dense cores which conceive and cradle young stars can be explored through continuum emission from associated dust grains. We have performed a wide field survey for dust sources at 1.2 millimetres
The Protostellar Origin of a CS Outflow in S68N
We have discovered a compact outflow of ≈ 80'' (0.12 pc) total extent toward S68N in the Serpens molecular cloud, which we have imaged in CS. We present outflow images acquired with the Haystack 37 m
Star formation in Perseus III. Outflows
Context. We present a search for outflows towards 51 submillimetre cores in the Perseus molecular cloud. Aims. Our first objective is to identify the protostellar population through the detection of
Star formation in Perseus - V. Outflows detected by HARP
Aims. Molecular outflows provide an alternative method of identifying protostellar cores, complementary to recent mid-infrared studies. Continuing our studies of Perseus, we investigate whether all
A Cluster of Class 0 Protostars in Serpens
We present new 12, 25, 60, and 100 μm high-resolution-processed (HIRES-processed) IRAS images of the nearby Serpens star-forming cloud core at FWHM resolutions of ~30''-1'. We use HIRES-processed
The Evolution of the Circumstellar Environment of Embedded Young Stars from Observations of Rare Species of Carbon Monoxide
Studies of the properties of the circumstellar material around young embedded sources can provide important insights into the relative importance of infall and outflow in clearing the circumstellar
Evidence for Pressure-driven Flows and Turbulent Dissipation in the Serpens NW Cluster
We have mapped the dense gas distribution and dynamics in the northwest region of the Serpens molecular cloud in the CS (2-1) and N2H+ (1-0) lines and 3 mm continuum using the FCRAO telescope and the
A new molecular hydrogen outflow in Serpens
We report the discovery of a new molecular hydrogen outflow in the Serpens molecular cloud. Narrowband filter images taken in the 2.12 μm v = 1-0 S(1) transition of H2 and adjacent continuum reveal a
Envelope structure of deeply embedded young stellar objects in the Serpens Molecular Cloud.
Aperture-synthesis and single-dish (sub-) millimeter molecular-line and continuum observations reveal in great detail the envelope structure of deeply embedded young stellar objects (SMM 1 = FIRS 1,
