Module Contents

class GaussianGalaxy(brightness, radius, **kwargs)[source]

Bases: lightcurvelynx.models.physical_model.SEDModel

A galaxy with constant brightness that falls of as a Guassian as the distance from the center increases.

Parameterized values include:

  • brightness - The inherent brightness at the center of the galaxy.

  • dec - The object’s declination in degrees. [from BasePhysicalModel]

  • distance - The object’s luminosity distance in pc. [from BasePhysicalModel]

  • galaxy_radius_std - The standard deviation of the brightness in degrees.

  • ra - The object’s right ascension in degrees. [from BasePhysicalModel]

  • redshift - The object’s redshift. [from BasePhysicalModel]

  • t0 - No effect for a GuassianGalaxy. [from BasePhysicalModel]

Parameters:

  • brightness (float) – The inherent brightness at the center of the galaxy.

  • radius (float) – The standard deviation of the brightness as we move away from the galaxy’s center (in degrees).

  • **kwargs (dict, optional) – Any additional keyword arguments.

compute_sed(times, wavelengths, graph_state, ra=None, dec=None, **kwargs)[source]

Draw effect-free observations for this object.

Parameters:

  • times (numpy.ndarray) – A length T array of rest frame timestamps.

  • wavelengths (numpy.ndarray, optional) – A length N array of wavelengths (in angstroms).

  • graph_state (GraphState) – An object mapping graph parameters to their values.

  • ra (float, optional) – The right ascension of the observations in degrees.

  • dec (float, optional) – The declination of the observations in degrees.

  • **kwargs (dict, optional) – Any additional keyword arguments.

Returns:

flux_density – A length T x N matrix of SED values (in nJy).

Return type:

numpy.ndarray
