The Effect of f(R, T) Modified Gravity on the Mass and Radius of Pulsar HerX1
The Astrophysical Journal, 2023 Millisecond pulsars are the perfect testable to examine potential matter-geometry coupling and its physical consequences in the context of the recent Neutron Star Interior Composition Explorer discoveries. We apply the field equations of modified gravity,

Complex Organic Molecules in a Very Young Hot Corino, HOPS 373SW
The Astrophysical Journal, 2023 We present the spectra of complex organic molecules (COMs) detected in HOPS 373SW with the Atacama Large Millimeter/submillimeter Array (ALMA). HOPS 373SW, which is a component of a protostellar binary with a separation of 1500au, has been discovered as ...

Starbursts in and out of the star-formation main sequence [PDF]
Astronomy & Astrophysics, 2017 Aims. We use high-resolution continuum images obtained with the Atacama Large Millimeter Array (ALMA) to probe the surface density of star formation in z ~ 2 galaxies and study the different physical properties between galaxies within and above the star ...

A unified model for galactic discs: star formation, turbulence driving, and mass transport [PDF]
, 2017 We introduce a new model for the structure and evolution of the gas in galactic discs. In the model the gas is in vertical pressure and energy balance. Star formation feedback injects energy and momentum, and non-axisymmetric torques prevent the gas from

Star formation inside a galactic outflow [PDF]
Nature, 2017 Recent observations have revealed massive galactic molecular outflows that may have the physical conditions (high gas densities) required to form stars. Indeed, several recent models predict that such massive outflows may ignite star formation within the

Star formation rates and efficiencies in the Galactic Centre [PDF]
, 2017 The inner few hundred parsecs of the Milky Way harbours gas densities, pressures, velocity dispersions, an interstellar radiation field and a cosmic ray ionisation rate orders of magnitude higher than the disc; akin to the environment found in star ...

The Constant Average Relationship between Dust-obscured Star Formation and Stellar Mass from z = 0 to z = 2.5 [PDF]
, 2017 The total star formation budget of galaxies consists of the sum of the unobscured star formation, as observed in the rest-frame ultraviolet (UV), together with the obscured component that is absorbed and re-radiated by dust grains in the infrared.

Early-forming Massive Stars Suppress Star Formation and Hierarchical Cluster Assembly
The Astrophysical Journal, 2023 Feedback from massive stars plays an important role in the formation of star clusters. Whether a very massive star is born early or late in the cluster formation timeline has profound implications for the star cluster formation and assembly processes. We

Stellar masses and star formation histories for 105 galaxies from the Sloan Digital Sky Survey [PDF]
, 2002 We develop a new method to constrain the star formation histories, dust attenuation and stellar masses of galaxies. It is based on two stellar absorption-line indices, the 4000-A break strength and the Balmer absorption-line index Hδ A .

Star formation is boosted (and quenched) from the inside-out: radial star formation profiles from MaNGA [PDF]
, 2017 The tight correlation between total galaxy stellar mass and star formation rate (SFR) has become known as the star forming main sequence. Using ~487,000 spaxels from galaxies observed as part of the Sloan Digital Sky Survey Mapping Galaxies at Apache ...
